See yarn in shop, yarn fairly screams that it wants to be a hooded mantle.
Bring yarn home, ball it up, swatch, figure out pattern, over the course of a year or so knit something like 5K stitches in bloody moss stitch because texture is pretty.
At the halfway point, start having second thoughts.
Suddenly realize yarn doesn't want to be a hooded mantle anymore. It wants to be a sweatervest.
Frog the mantle, re-ball the yarn, figure out pattern, cast on for vest.
The front's finished. Let's see if I can get through the back, assembly, ribbing, and blocking without it changing its mind again.
