I use yarn as decor. When my granddaughter pulled a skein of sparkly yarn from a shelf and expressed a desire for something made from it, I could not resist. It is sock yarn, so that limited the possibilities, but every little girl could use a pair of legwarmers.
Yarn: Wisdom Yarns Marathon Socks North Pole 'Balsam Fir'
Needles: US2 and US1
Pattern: None. I simply cast on 44 stitches, knit 2x2 ribbing on US2's for 4 inches, then switched to US1 needles for 4 inches. Finished by binding off in ribbing.
I was going to add stirrups, but that seemed like it would be too bulky for little feet.
