One skein of sock yarn should be enough for a pair of fingerless mitts. A Ravelry search for 0-150 yards of sock yarn found several patterns (41 pages of patterns in all categories actually, but some were a case of :the smallest size takes 150 yards).
Depending on your foot size you might be able to get a pair of footie socks out of 150 yards, particularly a low vamp style like these. Of course if you pick up a coordinating solid you can do something larger such as a "fakeisle" style colorwork hat or socks with a solid foot and colorwork leg (or if you match one of the colors, a solid foot and a variegated leg).
If you have any teenagers (or adults with an adventurous fashion sense) in your circle of family and friends that shimmer lime could make arm warmers or a shawlette or other accessory.
I'm rather stuck on the homespun though. Maybe a bandana cowl? It's very basic knitting, so the texture of the yarn has nothing to fight. Or a basic teapot cozy?
