OhJenny. Thanks for doing that video. I have included it on my print and cut page.

The carrier method has been used for many years (there's an excerpt from my 1998 book linked on the print and cut page) and only use the hinge method when the cut is too complicated or I want to use a printer that is not carrier friendly. I have been taking for granted that everyone already knew this method so I apologize for any confusion over when to use the hinge method.
Nelda's method using MTC only with solid colors is a great shortcut to what some of us have been doing with photoshop or scrapcoloring.com and will work in SCAL, except that SCAL only uses hex colors and not rgb colors (they are all the rage with the Imagine using them). Of course with a photo editing program or scrapcoloring you can use patterns as well as solids. Andy is hinting that he will be adding pattern fills in MTC so Todd, of you are listening, we'd love to have that, too, and the true import size for jpgs that makes MTC so easy to use for print and cut.
Again, you can find a bunch of methods on my print and cut page (many with new videos) and decide what works best for the project you are working on.
