Yarn Weight Question

Hi Everyone:

Just wondering if anyone has sewn squares together that are of different weights to make a blanket - and if so, how that turned out. I have enough squares to make a blanket, and while most are in worsted weight, a few were made with chunky yarn (this comes from trying to use up every oddball in the stash!).

Any recommendations on whether I could combine them in a blanket? Or would I be better off making more squares so that I had one blanket in chunky, and one in worsted?

thanks!
cheers
