There are three new free patterns at Donna's Crochet Designs and all three have pop tabs incorporated into them.
The first is a lovely layered Round Hot Pad. The pop tabs are added as you crochet. They are layered into this great circle pattern.
I think it may be may favorite of all I've done recently!
Next is yet another pot holder, but this one features pop tabs worked into a check pattern.
You see, you really can do just about anything with pop tabs and crochet!
