The first thing I ever knit, a small square for a cat toy. Stalled due to having no stuffing, and no desire to buy some. Finally hit upon the idea of using yarn ends for stuffing (after the horrendous experience of knitting in the ends on the Fibonacci Scarf). My first cabling swatch is included for good luck.
Actually, two other things contributed: starting this blog, so that I have to actually finish things to move them to the FO category; and wanting to make Cobie a cat toy to match his cat bed.
I also picked up catnip at the reptile(!) store today while purchasing crickets... Mmmm, kitty drugs:
