I tried Thangles, but then needed another size, you only get one size per pkg, if you want larger, smaller, buy another pkg. So, it is 9:30 in the evening and no LQS open, you wait until tomorrow. I had my LQS order Triangulations for me. Now, need a certain size? Go to computer put in disc, pic the right size, print it off, Voila, HST or Quarter sq. triangles whenever you want them and they are always perfect. Until I got this CD, I was verging on sheer insanity trying to make perfect HSR's. Now, no more problems.
