A really useful square ruler designed by Jenn Hogg and this version is exclusive to us at With This Cloth.
It starts at zero at both inside and outside corners, so you can use the ruler at the edge of your fabric or pattern, or on top of it.
There are seam allowance markers on every side plus cut outs to make easy work of adding a seam or hem allowance to your pattern. The cut outs are big enough for a chalk marker, to draw directly on to your fabric, and shaped so you can use an ordinary pen or pencil on your paper pattern.
You can use the inside corner to draft a deep facing and the whole fits neatly inside a box on a PDF pattern so you always know you've printed the correct scale.
Made in the EU in 4mm cherry wood veneer, finished by hand (by Jen!) with natural wax.
Available in metric or imperial measurements.
