Setting up a circular warp for sprang requires care. Setting up a long warp using fine threads demands extra care. Knowing this, I recruited the assistance of helpers. Local weaving enthusiast Paul Sparling volunteered. So did Sarah J Hull, who flew in from DC. She's interested in my work and wanted to participate, get an inside view ... well ... I expect she got an eyeful.  The experience of the first time through the creation of such a sash told me I'd be wise to have someone watching the cross and counting the threads. The cross absolutely must be 100% correct for the centre of the cloth to be error-free. Paul did this job admirably. Experience has also shown me that tending the umbrella swift, seeing that the threads came off the hank smoothly is another critical job. I've since decided that the stirring of the pot in the dying process tangles the threads slightly. Better to dye the threads first, and then combine into hanks, so that they are less tangled, come off the swift more smoothly. This makes for more consistent tension in the warp.  The next step is to work the initial row. It's important that each stitch is correct. Any error will show up at the very centre of the work. The challenge is compounded by the fine size of the threads, and even more so that I am working with pairs of threads. Each stitch needs to use the correct two pairs of threads.  Slight differences in tension mean slight differences in lengths of threads. This causes horrible tangles when pushing to the mirror-image side. I am stuck in a nightmare. It's like Red Riding Hood facing the wolf. Now, I know how the story goes. I know that the kindly woodsman enters the scene in time. He deals with the wolf, and there is a happy ending. I know from experience that the un-even-ness does work out ... it's just that I'm not there yet. I'm still staring at the open mouth of the wolf. But the interlinking stitch does have amazing forgiveness. And the silk strands are very strong ... will not break (just trusting that knots in between the various skeins hold tight). The un-even-ness will work out  The first step in making the replica sash is ordering the yarn. According to my records, the size of silk I need was called "machine embroidery silk". Yes, it's the gauge of sewing thread. And it needs to be reeled silk, not spun silk. I'm wanting my sash to be able to do the job that historically was its purpose: to transport the wounded off the field of battle. More about that later.
The original sash featured pairs of threads in the warp. The threads were not plied, but rather sit parallel in the sash. This seems to be typical for sprang sashes from eh 1700s. The reason for this, according to Coby Reindeers-Baas had to do with rules set by weaving guilds in Europe at that time. There was strong bias for "spindle spun" thread as warp (as opposed to "spinning wheel spun" thread). I've decided that the first thing I need to do with this silk, is to combine skeins, putting them into skeins of parallel threads.
The next step will be dying the silk. I sent three small samples to the curator. Waiting to hear what she thinks, whether or not any of those reds will be the color they want.
The portrayal of Jacob Fugger by Albrecht Drürer leads me to think that Mr Fugger wore a sprang bonnet. I tried to make a similar bonnet. I interpreted the heavy lines in the bonnet as lines of horizontal twining in a sprang bonnet. When I tried this myself I found that there may be a reason for the twining in the sprang bonnet, as you will see.
Thinking about approaches to incorporate horizontal twining into the sprang cloth, I thought of two ways to do this. One way (method #1) is to create a line of weft twining as I created the cloth. The other way (method #2) is to add the twining stitches after completing the sprang. The twining stitch does not have the stretch of the sprang cloth. Maybe, indeed, this was the whole idea of the twining line. This risk of method #1 is that the line of twining is too narrow for the desired width of the bonnet. I found method #2 to be more effective, in that I could place the sprang cloth on a head shape (styrofoam head) and then work the twining stitch at the desired tension, creating the desired width of the cloth, fitting the bonnet to the head. How did I work the twining stitch?
How do you tie the bonnet on the head? Two approaches come to my mind.
If you want the ends of the band to pass all the way around the head, then I would pass both ends through the circle at the back of the head.
To make such a bonnet, I set up a 16 inch long (41cm) warp of a dark green 2/8 wool and a worsted weight yellow, alternating 10 green and 2 yellow, ending with 10 green.
I worked the green threads in an interlinking stitch, and the yellow threads in a vertical twining stitch. I described the vertical twining in my post of Feb 2, 2023.
To gather the end loops, I divided the end loops into two groups, separated by color. I slid one color of loops on one blunt sewing needle, and the other color of loops onto the other blunt sewing needle.
Dividing the loops in this manner allows me to snug the loops into a far smaller circle.
When the loops are tightly gathered there is a reverse-widow's-peak in the centre of the forehead. To avoid this reverse widow's peak, I reserved the dark loops at either edge, did not include them in the gathering. Instead I stitched them together in a tight seam at the centre front of the bonnet.
The reserved dark loops, sewn together at the forehead, make for a smoother line to which I could attach a brow band. The brow band is a length of weaving, made on a tape loom. I gathered the loops at the back of the bonnet in a fashion similar to the treatment of the loops at the front of the bonnet..
I stitched the brow band to the front 3/4 of the bonnet, leaving the band free at the very back of the bonnet.
 The portrait by Lucas Cranach, painted in 1526, of Katharina Luther, wife of the famous Martin Luther, depicts a woman wearing a hairnet. It was Dagmar Drinkler of the Bavarian National Museum who showed me this image some years ago. It is her opinion that Mrs. Martin Luther is wearing a sprang bonnet. I interpret this as possibly an interlinking structure, what I call a doubles grid.
Arriving at the centre, I chained across to secure the cloth. I chained threads one at a time. 
Then I blocked it. I got it soaking wet, and then selected the right sized mixing bowl from my kitchen.
Mrs Luther's bonnet seems to have a band around the rim. I made a band using my tape loom. I measured out threads of sufficient length to make a band that will go around my head three times, plus a bit extra to tie a knot.
I made this first bonnet using a pale wool, hoping you would be better able to see the details of construction. Mrs Luther is wearing a dark colored bonnet. You will also note that the band around the head is rather wide, far wider than the band I made for this pale-coloured bonnet.
I worked a band in a 2-2 interlace stitch, with vertical ribs, and a 4 contrasting colored threads. OK, the red yarn I selected is rather close in color value to the dark green, and the green design does not stand out well on my band. I was also disappointed to note that the design in my band is far more elongated that the design in Mrs. Luther's bonnet. OK. Maybe I should stick to my field of expertise, the sprang, and leave the band to someone else. Perhaps it is another technique, perhaps an embroidered design.
Since I've got time on my hands, all travel plans cancelled, I figured I should put my efforts to a project worthy of a great deal of time ... all those lace patterns. I've seen sprang lace in a number of collections, have photographed them, and have made some samples. Now is the time to sit myself down and to go through these, one by one, and render patterns that will be read-able to others.  The inspiration for these patterns come from several sources. There's that book of sprang sashes, repaired by Coby Reijndeers-Baas, sashes with all manner of designs, people, boats, deer, mermaids, and a variety of geometric designs. Then there is that collection of lace from the Cinquantenaire Museum in Brussels that I visited back in 2013. Other lace patterns come from pieces in the British Museum, the Victoria and Albert Museum, the Petri Museum, and assorted other collections.
I'm working on putting the patterns onto a grid, so you'll have a grid pattern. From that grid, I'm deriving a "written pattern" that will read "right-edge stitch, 3 plain stitches, left-edge stitch". Having done that, I then set up a warp and make an actual sample, to check my pattern, and to be reasonably sure that the pattern is correct. I'd be very happy to have others check these patterns. If you're interested, send me a message by commenting on this blog, or to the "contact me" on this website.
I visited the Kelsey Museum collection in the spring of 2016, went home and worked out the pattern for this hat, and then came back in the summer of 2017. At the occasion of my second visit, I took a photo of my replica beside the original. Actually I took two photos. In one of them, my replica is inside-out.   If anyone is interested, my SprangLady website contains three tutorials that take you step-by-step, showing you how to do this twining technique on a background of interlinking. And I do still have the specific pattern for this bonnet.
Last Summer I made a scaled down copy of the Braddock-Washington sash for Carlyle House. The word is that the display is now complete, and viewable to the public. Here is the photo they sent me, the mannequin wearing the general's uniform .... complete with sash.  En route to the British Museum, I stopped off to visit a friend who lives near Sheffield. I met Andy and Elaine a few years back. Elaine really wanted to know more about sprang. They were, at that time preparing to participate in an event, re-doing the battle of Marathon in Greece ... he was going to be one of the bad guys. I made him a pair of leggings, appropriate to the time period, and based on research by Dagmar Drinkler.  It seems that Andy has worn these leggings to several events. Imagine my surprise when I read on the internet that sprang is not at all suitable for leggings! Andy showed me a post indicating that, with one broken thread, the pants will fall apart. This, I thought, is the perfect moment for a bit of testing, some experimental archaeological if you will. Andy allowed me to cut a thread in his leggings. To make it a fair test, I cut a thread at the knee, a place that would be affected by movement of the leg.  Andy took a picture of me cutting the thread just in front of his left knee.  Here you see the broken thread at the left knee. Andy then went outside to do some work in the yard.   He cleared his deck of the leaves, and tended to his leaf-blowing machine. His leggings stayed on the entire time ... no falling apart ... no falling off. Indeed no increase in the size of the hole. The wool threads stayed put.  Wool has a certain 'grabbiness' to it's surface, and the wool sock-yarn that I had used to make the leggings is no exception. Yes, I've seen silk sashes in museum collections with long vertical slits, where a thread broke. The slipperiness of silk as well as the simple interlinking structure would allow a slit to develop ... but the slit will only open up so far. At some point the length of the cut threads will, itself, prevent further un-doing. The structure of the zig-zag pattern in these leggings also helps prevent un-doing. I repaired the damage I had caused, tied a knot to mend the cut ends, and tucked the knot to the inside of the leggings.  The damage is now repaired, the knot almost imperceptible.
A big Thank You to Andy Cropper for permitting me to carry out this test. |
