If you use all three you will see how to weld, make a mat( or shadow), make cards, edged mats, frames, monograms, matted cards and number cards.
No rocket science but enough basic techniques to get the creative juices going for both card makers and scrapbookers.
I know that you've been helped immensely by Jancy and others with their instructions and I do not wish to tread on any toes - these tuts are in pictures as some people learn better that way.
Enjoy
