it sounds like everyone has tried most of the methods here...Thangles, Triangle Paper, Triangulations. ALL very interesting possibilities! I *heart* things that make my piecing more accurate, so I am a pretty big fan. I did a bear paw with triangle paper and though I am not a fan of tearing off the paper (and the mess that makes) it sure came out perfectly.
Aside from accuracy, the main advantage to the Thangles is that you are cutting your fabric into STRIPS which are usually an even size (such as 2 1/2 inches) rather than cutting squares and triagles which are odd sizes (such as 2 7/8 inches)
And I find the main difference is that Thangles uses strips, triangle paper uses pieces of fabric (such as a fat quarter), and then you rotary cut on the lines on the paper to cut into your HST's.
Triangulations (CD ROM) is for those of us (like me) who live in the middle of nowhere and can't run to a shop to find just the right Thangles if you run out or Triangle paper. A package of triangle paper does last a good long while, but you never know... All you do with Triangulations is load the CD into your computer, load the paper you want to use into your printer, and print as many as you need forever and ever and ever. Way convenient, economical and LOVE IT!
I have found a web site that allows you to print HST papers on your computer. Good for trying it out and a small project. If you use this be
very careful that when you print, you have set your print options to
none rather than "scaling to fit" or a percentage other than 100%, or the printed sheets will be ever so slightly off and you will not get the right size. [ask me how I know this! :cry:] Be sure the reference square on the printed sheet measures 1" x 1"!!
If you want to give the technique a try, have a go at it:
