The idea : you cut a plastic straw to the size you want.

You cast on some stitches and you knit in the round. At least, you knit around the straw itself.

It is totally useless, but very useful to use you little remnants from a previous project.

You will also need a set of three 3mm DPNs.

The English version is in page #3, so you have only to print (if necessary) one page.
