Hopefully R-Sea will also answer this m-fay! There are different kinds of gadgets/templates for "add enough". I have an actual ruler that makes it so much easier when making half square trianges etc. OR if you are using a paper piecing pattern that doesn't include the 1/4" seam allowance. On-line patterns often don't include it. So with the Add-enough, you just drop the ruler/template on the edge & your 1/4" or whatever amount you need, is right there to add on to your templates/patterns etc. I'm a mathematically challenged gal & apparently can't measure consistently! lol So this tool was a great addition to my tool box!
