I plugged my gauge into the Sigma pattern today. Cast on.....240? Oh, dear. I'm getting all flustered just thinking about it. Obviously I haven't made a grown up sized garment before, but that just sounds like an awful lot. Especially since my method of casting on usually includes many instances of losing count, counting from the beginning, losing count again, recounting, losing count again, recounting, and then running out of yarn for the double cast on about 15 stitches from the end and having to start the whole flipping thing over again.
I know I should just place a marker every twenty stiches or so, and save myself the raised blood pressure. I think 240 stitches may be the scare I need to actually start doing that.
