The add-an-eighth ruler is the best tool for small paper piecing projects. It will easily add an eighth of an inch as seam allowance, instead of the normal quarter of an inch. This will make your seams less bulky. So if you’re going to make a foundation paper piecing project with tiny pieces, this ruler is what you need! The PLUS ruler is a little bit wider, which gives you more grip when trimming off the fabric. And it also has a tapered edge which helps folf back the paper while doing foundation paper piecing.
