I started this with a "new for me" cast on, the Twisted German Cast On. This is like the Long tail, but is more elastic and good with the ribbing at the bottom of the tank. theknitwitch on Youtube has a great video on how to do it. I, however, really suck at either of these cast ons because I can't seem to guesstimate how much yarn it will take to make it work. One day maybe I'll figure it out.
Heh. See that orange thing at the bottom right of the pic? Yeah, my kids have been there again. It's a pumpkin stencil that someone dug out of the toy box and it mysteriously appeared on my desk. Imagine that. See that ziplock bag? Yep, my knitting tool kit. One day I will either make or buy me a cute little bag to replace it, but for now, it'll do.
