I got a chance to play with the new version of the Cricut Design Studio that works with Vista 64. In the example below, let's pretend that I want to cut the elf only and not the gift that is part of this cut. I can click on the gift, line by line, meaning that I can take away all or only some of it, then right click and click on 'Hide Selected Contour' to remove the highlighted section piece by piece. Now when I cut, I'll only cut the elf. Cool huh.
