Clearly Perfect Angles

This is such a super useful tool to keep permanently on your sewing machine!! The new generation one even clings to the bed of the sewing machine so no need to stick down with tape.

It is a great tool to sew accurate half square triangles and 1/4" seam allowance in general.

There is a very useful Youtube video that shows you exactly how it works (instructions are of course included in the pack too).
