If you decide to donate sections locally or to Warm Up America directly, USE THIS FORM to track your donations and to enter a special Sectional Blanket giveaway through December 31, 2022!

Sectional Blanket Pattern Notes
- Whenever possible, I recommend crocheting over your yarn tails as you work. Sometimes, a stitch pattern will be too lacy to effectively crochet over your yarn tails. In that case, I recommend weaving in ends.
- Fiber Flux has a helpful video tutorial for crocheting over your yarn tails as you work here.
- Stitches n Scraps has helpful video and photo tutorials for 3 ways of weaving in ends here. I use the yarn (tapestry) needle method.
- Color changes are only suggestions. You are welcome to change colors more or less often.
Abbreviations Used in This Pattern
- CE – Color E
- ch – chain
- sp – space
Notes for Section 21
- Color changes are only suggestions. You are welcome to change colors more or less often. For this section, my Color F is WeCrochet Brava Worsted yarn in 28422 Cornflower.
