Flexible curved ruler 50 cm

The perfect ruler for fitting and manipulating curves.  Use the ruler to determine the shape of your crotch curve and compare it to the trouser pattern that you are about to sew.  Match the curve of your hips to the curve of the pattern.  Did you adjust a shirt pattern and now you need to check that the armhole and sleeve will still fit together nicely?  Simply curve the ruler along the pattern piece and read the length of the curve!

This flexible ruler measures 50 cm/ 20".  It is 3/8" wide.
