You can use any shape at all! If you don't have cookie cutters, just use the top of a cup and make simple circles. Or cut out hearts with a knife. I am going to make some house shapes to sell in my store, I think. They have a primitive look about them...and they smell SO good! My daughter chose the dog bone in the picture...she picked out weird shapes like question marks and the number 5. I have like 100 cookie cutters to choose from. I'll be making my own batch soon. I have to get some more cinnamon!!!
