These were conceived as a stashbuster project, so when I ran out of yarn I thought, Great!, grabbed the only other color of that yarn that existed in the stash, and knitted on. The color change isn’t very visible unless I kick up my heels or something. Just knowing it’s there gives me great amusement. 
Pattern: Pebble Rib Slipper Socks, Creative Knitting (September 2006)
Yarn: Bernat Softee Chunky scraps in Antique Rose and Carnival
Needles: Susan Bates Silverado 32″ circular and Pony Pearl dpns – both US 10
Those are so cute — and I love the color change! Since I got hooked on those Mason Dixon ballband warshrags and realized how great they are for using up leftover bits of cotton yarn, I’ve been wishing that more knitting patterns were like that…I think I might even have the magazine with this pattern in it!
