I made this ruler holder because I was always covering up my rulers or losing them,this is not an original ,Ilearned this in a class.
there were no set size it is to your preference and what size rulers you own.
start with a 29 by 60 upholstery fabric,I got mine off the bargin table at hancocks,it will fit on the back of the door in your sewing room,my sewingroom is very small,
use a iinch hem, all the way around,lay out your pockets according to your rulers,I embroidered on each pocket the ruler size.
the top pockets are out of clear vinyl,that holds myratary cutter or what ever,25by6.I used a dowel rod to hang the
