The needle sizes are US sizes 7 and 8. I just making this silly baby blanket for my daughter's baby due in Sept. I've started and stopped this thing 100 times changing yarn, needles, etc. You'd think it was being knitted for the King of England the way I've fretted and fumed over it. it's fuzzy chenelle yarn, so you don't really see the definition of the stitches, so I guess that's my problem. I think I'll just stick with the 7 since that's the larger size of what it recommended. Does that sound like a good idea?
