This is a great use for leftover yarn! Recently, I bought some cacti and succulents, but I didn't have a nice pot to put them in. So while I keep searching for the perfect planter, I am using an old ice cream tub. Of course it looks terrible, so I got some of my leftover cotton yarn and quickly crocheted a simple striped cover. Made in a long rectangle, I sewed the ends together and slipped it over the tub's side. Easy! I love it.
How have you used leftover yarn?
