This works perfect for small coffee cups and water bottles. I have also used it for storing my sun glasses in.
Materials:
1 skein of sock yarn (Tofutsies)
5 size 3 double point needles (or your choice for knitting in the round)
Instructions:
Cast on 64 sts
Knit in the round using pattern k3, p1
When you have reached the desired length start your decreases as follows
Needle 1; k1, ssk, k to last 3 sts, k2 tog, k1
Repeat for other needles
Alternate a decrease round and a plain knit round till you have 24 sts left
k to tog all the way around
k 1 round with no decreases
Slip all sts onto yarn and pull tight.
This will form the bind off and a flat square bottom.
