The yarn is Knit Picks Chroma Fingering in Theatre.
I wanted to be able to finish it with just one skein of Chroma, so I only cast on 81 stitches for the initial triangle. I had enough yarn in the end to finish 9 triangles, but then not enough for a nice finished edge, so I ripped back the last triangle and had a bit of yarn left over.
Now the real question is, do I keep it for myself or give it away for Christmas?
