Lance PGS-1-LAN Pattern Grading Scale Ruler, 8.5"x6", Clear Plastic

Trouble with fractions? This is the tool for you. I know where to find these measurements on sewing machines, but adding specific little seam allowances to patterns and making small adjustments can be a pain on certain rulers. I bought this with a Tailor's square and two different lengths of French curves. Even though I live on the East Coast, with shipping all of these essential drafting tools were cheaper on here than getting them from Amazon, Mood or even my local sewing spots.
