No-Frills™ Serpentine Rulers

The serpentine rulers are based on a wave that will intersect the seam junctions on 4" & 1 1/2" blocks and the 3" & 2" blocks. It assists in a perfect continuous curve on double Irish chain blocks as well as any others continuous curve through these size blocks.

Also wonderful to mark spines of feathers to go around corners or some of the wonderful freehand designs with leaves and loops etc etc
