I have five of the June Taylor rulers and am using at least one of the rulers each day. I have one for cutting eights. I never did like cutting something ending in 3/8 or 7/8 with my regular ruler. With that June Taylor ruler, eighths are a breeze! Another ruler had slots every 1/4 inch. I accidentally ended up with two of the 1/2 inch slot rulers. If I have to cut 6" blocks, I use a tiny strip of masking tape to make 6" increments on the ruler. If the pattern also calls for 3" blocks, I mark the second ruler in 3" increments. The 2 1/2" slots ruler lets me quickly cut binding strips or to cut out 5" squares. Seldom do I cut out a quilt without using a June Taylor ruler for almost everything. I have an electric Accuquilt Go that I use for cutting circles, ovals, and unusual shapes. For straight lines, I am addicted to June Taylor rulers.
