It’s Octagon Time! It’s a blanket/basic shawl. Really, what it is depends on what you want to make, and what yarn you use.
I went a bit wild and self-indulgent on this one; it is probably the most hedonistic use of an expensive yarn I’ve ever committed. The soft blue gradient yarn making up most of the project is Cascade 220 Superwash Wave in Deep Sea; the bold near-neon-green stripe is Dream in Color City in Pickleball.
(The smaller stripes are Malabrigo Yarn Rios in Apple Green, and the subtle, thicker bands are Malabrigo Washted in Aguas and Cirrus Gray. It was meant as a scrap-friendly project, and technically it is that, but I kind of like the Cascade background and the contrasting stripes. The .PDF is written as a formula, and doesn’t really include instructions for stripes. If you’d like to knit something with a similar color pattern, I had about 16-18 garter ridges separating all the bright green bands, and stayed pretty consistent with that all through the blanket. The middle might be the smallest band of main color; it’s about 14 ridges.)
Weirdly, despite the hedonism and all my feelings about it, I really like the result, and want to keep it, and not allow the dog to steal it; something about the murky blue-greens and the shocking contrast stripes really appeals. (I will probably keep it. It’s a small throw and not really adult-sized, so something that’s a dog or a kid will probably end up with it eventually. Maybe not the dog though. She got the Garter Square blanket sample. Makes her tacky dog bed look slightly better.)
