I just made a Mariner's Compass block with hst using Triangulations 2.0. It was only the size that goes with the pattern but I'm thinking of getting the Triangulations 2.0. I thought it was easy and made bunches at a time and the squares were perfect! It's basically a disk of pdf files:
Triangulations 2.0 takes half-square and quarter-square triangle construction to a whole new level. Imagine the freedom of having any size triangle foundation in your hands at the touch of a button.
Runs on any PC or Mac computer with Adobe Acrobat Reader
Half square triangle foundations sizes 1/2" to 7 1/2" in 1/8" increments!
