If you a set of calipers you can use them to measure the diameter, then go to a knitting website (knitpicks.com for instance) and compare your measurements on their knitting needle chart. Or, you can take them to a knitting shop and ask them to size them for you.
I do a lot of sewing and walmart here has stopped carrying any fabric .so i have to get everything on line .shipping kills me .i make aprons skullcaps .i also make computor tables which are wood and stuffed on the bottom .i do a lot of military as a belong to the vfw here and we have a flea market on weekends to make money to support out veterans
Thanks for supporting veterans! I am one, a young one....But still one! I know all about living where we are lucky to have a Walmart too. I have to drive an hour to shop at a super Walmart...Ugh it is horrible. There is a small one about 30 minutes away, but no food. Rural living stinks sometimes. That's why I try to shop when there is free shipping or special deals!!!
