When we first got SCAL we were wondering how are we going to save paper on cutting a pattern that has multi colors that needed to be cut. Well this technique that the video goes though should help you with this. The video goes though two different ways to accomplish the same goal. We know that there are other methods out there, but these two work just fine.

Its a video tutorial I hope this may help some of the new beginners who are wanting to size things up and making them match proportionally to the original artwork.
