Can't Stop Spiral Stripes

Having fun with stripes. I've done 3 pairs now and I can't seem to stop. Help!
First pair.

Second Pair already given away to a grateful sock wearer. 

Third pair, have run out of most of light gray so picked up some blue. This system of spiral stripes works much better with a traditional heel flap. Happier with these.

Since I can't stop I'm scrounging around for more part balls of worsted weight yarn. But I'm going to switch to hats for charity. I can use even more little bits of yarn. Yay.
