This is a quick post showing how a strip set can be used with the 8-1/2″ Quarter Square Triangle die. The strips are sewn together–either two strips or four strips into a tube. Then lay them on the die and center as carefully as possible side to side. The strips will not reach the outer blades along the long edge, but the strip set needs to be centered between them as evenly as possible. These blocks all turn out the same size–remarkably. However, the final size may not be an even number. Here are the photos that tell the story.
This is an example of a block that might be squared up using a technique shown here. And the reason is that you may want your blocks to be an exact even size.
