I don't know about Triangle Magic. I have Triangulations and I really love it. I copied the CD onto my hard drive and put the CD away with my other backup media. I can print from my hard drive (which is faster on some computers) and not have to worry about digging out the CD every time I need to use it.
If Triangle Magic has HST's in 1/16" increments, plus instructions for QST's and flying geese, it might be just as good as Triangulations. And it's about the same price.
One thing missing from the Laundry Basket Quilt papers that I really wish was there, is the marking that shows you where to cut the bunny ears off of the blocks before you even press them open. That's one of the best things about the way that Triangulations prints.
