Hiya Melmac51! We'd love to have you "play"!
Circular needles are super easy. When knitting something flat, like a blanket, you use them so that they will hold more stitches. It stays knit flat because you never join the yarn to make a circle. when you get to the end of a row, you just flip it over and start again. The only difference between circular needles and straight needles is that there aren't 2 needles, you just use the other end of the circular as the 2nd needle.
Trust me, this will make sense!
I do need another knitter for our blanket "buddy" which is all acrylic yarn. We just use 2 strands of worsted weight held together. JDee is working on it right now. If you want, I can add you in, and have Yarncharmer be the finisher of the blanket.
If you get the blanket and don't know what to do with it, or get stuck, just post in here. Lots of us check every day, sometimes 3 or 4 times a day, and will get back to you right away!
Could you pm me your address and info so that I know where the blanket will get mailed to?
