I tried the method in the video below for making a nine-patch. Yes, it does work and yes, it is pretty accurate. The problem is you can't just make any nine-patch. I thought this would be great for quickly using up all those nickels. Nope! To use a nickel you must make 1.66 inch cuts and they don't put those markings on our rulers. Most sizes are not easily divided by 3. So, if you don't care much about the size of your nine-patches, you might like this method. Personally, I don't have much use for the sizes you can easily make. That's my opinion and I'm sticking with it.
