Please post your ideas for how to make boot cuffs that stretch to fit all sizes of calves. Some ideas I know of:
- Knit, don't crochet. Crochet doesn't have much stretch or resilience.
- Knit with vertical ribs.
- Use acrylic, wool, or wool/acrylic blended yarns.
- Look for yarns with an elastic thread. I've heard that it's possible to knit an elastic thread into any yarn, but I've also heard this is not easy.
