I was looking for something that could cleanly cut through four layers of fabric, two layers of wool, and two layers of lining. I made a fabric book and needed to install some 5/16 inch grommets. What a wonderful tool this is! This worked great and I have a choice of sizes to use. And it is fun! Pieces of fabric are easy to take out after punching, either by blowing through the side of the punch or by pulling/pushing them out with a needle or something. I can only recommend this remedy! And they come in a nifty little box!
