Tri rulers come in 3 sizes. 20", 14" and 6"

These rulers are just wonderful for diagonal crosshatching! I have just used the 20" one to diagonally crosshatch an 18" border perfectly. You will definitely need the largest extended base for this one, but the actual weight of the ruler itself gives it stability without any pressure from yourself. The smaller rulers are a lot easier to handle & perform really well in smaller, more common situations.

Please contact me for a price on the 20" ruler as this is a very large ruler & will only suit the largest of quilting machines...
