Nalbinding the small batch of thinner tapestry yarn kind of made sense, since it requires you add more yarn as you go by felting the end of the new piece to the end of the last. If the skeins that had felted together were an indication, tapestry yarn felts well.
I cast on and made a big loop, thinking I’d make a bag rather than another hat. I choose a new colour every time I added more yarn. As before, the fabric tightened up as I worked, and after several rows fit comfortably around my head, so it became a hat after all.
Now I wish I’d measured the initial loop so I could work out the percentage of shrinkage. Counting the stitches might give a rough idea, though how long that actually is may depend on the yarn thickness and how tightly I stitch.
I really like the way the colour stripes look. I’d like to try doing this with a slowly changing graduated yarn. I’d also like to try making a mobious scarf, as it would be easy enough to add a half twist before joining the loop. There are other approaches to try as well: starting at the top of a hat and working down, and seeing if I can find a way to nalbind back and forth rather than always making tubes.
Now that I’ve made three items, I’m pretty sure I like nalbinding. It’s portable like knitting. It’s stretchy, though not as much as knitting. It doesn’t seem to bother my hands like knitting does.
