Strip Sets are a fast and easy way to finish many types of blocks but sub-cut widths are often curved. The result is blocks that are not square. Bloc Loc’s Strip Set Ruler locks onto the seam of a strip set so the sub-cuts are straight and blocks end up square. Will sub-cut up to 10” in length and 7” in width. There are bold lines every 2 1/2”, which is perfect for Jelly Rolls. Will work with any number of strips as long as they fit under the ruler.
