I just found what I'm going to knit to keep my glass needles safe. I have 2 pair from GB Glass. I also noticed she hasn't posted any on EBay lately. I have another pair from EBay, although I can't remember from whom. "Splendid Stitiches" I think.They're all made of borosillicate (ex. Pyrex) so they are quite strudy but I'm sure not completely unbreakable. They are very slippery to knit with. I haven't used them much really, but they do "work"
Anyhoo, iI have the 2nd issue of Magical Knitting from Cat Bhordi and there are felted needle cozies in it I am going to make for my glass needles.
Here's a previous post with pics of my glass needles. As I mentioned there, the pics don't do them justice!
