Left Over Sock Yarn

One of the by-products of being a sock knitter is that you accumulate leftover sock yarn.  I have a few bins of leftover sock yarn.  (yes, bins - that's not a typo).

Sometimes, in my head, I plan to make the most epic sock yarn blanket ever! I haven't cast it on yet, there's always too much other knitting to do.

There are lots of things to do with leftover sock yarn.  You could:

*create a magic ball  and then knit all the things with it.  (my magic ball would be the size of a beach ball)
*create a blanket of mitred squares - these seem so popular right now.
*make a Beekeeper's Quilt. (confession: I made a few of these hexipuffs then got bored so I stuffed them with cat nip gave them to my cat)
*make small toys or amigurumi projects.
*create mini skeins to trade with and gift to your yarnie friends.
*make cup cozies.
*make earbud cozies.  (I really like these)
*make chapstick cozies. (these make great keychains)
*yarnbomb something!
