Here is a link that might be useful: Plastic circular knitting needles

Thank you. I did the same, and looked through a lot. I bought a three different type needle-set, from Knit Pics. I'll try to find a size 9-plastic circular next.
Thanks.

i think mine is a 8 that i have

I have bought a couple from Wall mart.

You're lucky. I haven't seen any in our nearest WalMart. I'll try again. I like needles that are more pointed, as opposed to blunter ends.
