Congrats on having your 1" GFG nearly finished! If you google "Insanity Quilt" you should come up with several quilts using 1/2 inch hexies. Someone else on this thread mentioned 1/4 in. That lady deserves a Purple Ribbon for sure! I have done a few 1/2 in to use in applique border. They are so cute, but don't think I'll start a whole quilt very soon! Have fun! You can do it!!!
