A quick tip for using up those scraps of yarn that you might have leftover after a project: pockets.
Whilst there are a number of patterns specifically written for small amounts of leftover yarn, such as the beekeeper’s quilt, sometimes you don’t want to commit yourself to such a large project (my beekeeper’s quilt was a long-term stashbusting project).
Instead, those little scraps are perfect for pockets. Use the yarn from your project to pick up the initial stitches for any pocket, and work a few rounds with it, but after that you can switch to scraps and leftovers, safe in the knowledge that (unless you turn your pockets inside out) no-one will ever know that the pocket isn’t all the same colour. This also allows you to maximise the use of your main yarn without it being hidden away.
