Quilter's Groove Rulers ~ ProLine rulers 

Measuring and marking are overrated. I developed these rulers to eliminate the need to mark and measure. There are 5 different sizes.. ProLine 1 does 1" spacing, ProLine 2 does 1/2" spacing, ProLine 4 does 1/4" spacing, ProLine 8 (my favorite) does 1/8" spacing and ProLine 16 does 1/16" spacing.
