A few years back I used some of my single spun wool to make a bonnet. The wool was quite dark in color, and does not photograph well.
I’ve since made another bonnet, this time using some commercially spun linen.
The pattern is based on a bonnet in the collection of the Danish National Museum in Copenhagen. The pale color in the linen makes it easier to see the stitches.
It is really a few simple stitches, combined to make an interesting pattern and a lovely bonnet.
Now, examining historic hair nets, some of them were made from tightly spun singles. I experimented with some tightly spun wool, not treating the overtwist, nor waiting for it to settle down. It worked just fine. The weaving was easier than I expected, not really hampered by the extra twist. The finished piece, well, yes, I soaked it and blocked it twice, but it looks just fine.
