So, I finished the back of Matt's vest, did a little dance, and got right back to work. I cast on for the front.
When I cast on, I did something new. I placed stitch markers every ten stitches. This way, I only needed to count to ten, something that even I can do with relative ease.
A lot of you do this when you're casting on a large amount of stitches, for something like a lace shawl. Perhaps I'm just getting warmed up!
