Here is a simple way to make your multi-colour yarn more manageable. Buy a cheap-as-hell makeup bag from your local cheap-as-hell toiletries department (i.e. Superdrug).
Haphazardly wedge the sides of this bag under a hole punch and punch away until an acceptable quantity of holes has been reached.
Thread the ends of some lovely centre-pull balls of yarn through said holes, zip up the bag and enjoy your delightfully transportable tangle free knitting. Trains, cars, waiting rooms, funerals, knit wherever!
Here I am using two lovely balls of Sweet Clement Smitten II to make a fancy striped sock (I took the seam idea from the Garden Gate pattern). It’s a very simple hack, about one step up from using an old loo roll to wind those centre-pull balls, but I’m pleased with it!
