I have a bit of a newbie question...I have done some knitting before, but nothing super complicated. I'm wanting to try a pattern for a baby blanket, that says that I need 6.5 mm needles...now, I was going through my grandma's needle collection, and she had both 6 and 7 mm needles. Would it be okay for me to use .5 of a size down? Or would that throw off the gauge too much? (this is the pattern I'm looking at, if it matters: http://www.lionbrand.com/patterns/60080A.html?noImages=
) The only reason I ask is, I'm just hesitant to spend more money on a new set of needles if I have some that will work.
Thanks a lot for any advice!
