Rainbow glass cover

Its finished and I'm very happy with it. Its a simple pattern.
Start with 6 in a ring,
Working in single crochet throughout, increase evenly by 6 each round till the base is the same size as the base of the glass you are using.
Now do one round working in the back of loop only
Then continue going round single crocheting without increasing until you've got the height you need to cover the glass.
This used about half of a 50g ball of sock yarn but you can use any weight yarn as long as you use the corresponding crochet hook. It'll be great for using up odds and ends of yarn.
Happy crocheting x
