## A Word from Claire de Lune Fiber Arts

This pattern is designed by Allison Bostrom, the designer, creator, and very-much-still-learning photographer/social media manager behind Clair de Lune Fiber Art. She designs stimulating crochet and knit patterns for everything from garments and accessories to homewares. Her goal in writing patterns is to encourage makers to learn new stitches and construction techniques, or to reconsider the ones they know. Though working with yarn is always relaxing, she finds real joy in pushing herself to do something new and different with yarn.

You might remember her from her beautiful Umbral Shawl Knitting Pattern she shared on the blog.

### Pattern Notes

- As written, this pattern is for an 8”/20 cm afghan square. It consists of a butterfly cable on a seed stitch background. The seed stitch border is worked at the same time as the cables.
- Larger squares can be made by using thicker yarn and bigger needles and/or adding more stitches and rows to the seed stitch border.
