i think you should save your money and look at the easy ways to make triangle squares. the down side of using the accu-cuts and cutting triangles to sew is the bias edge that stretches and gives waves. if you always start with a 2 squares, right side together, draw diagonal like, sew 1/4" on each side of that line, cut on the line flip open and press you have 2 perfect 1/2 square triangle blocks with no stretchy bias. sometimes the (aids) may make them go faster(i dont get this but some say thangles make it so much faster) but before finding the short cuts maybe finding the technique should come first...just my thoughts. ... and i have a friend, been quilting for 30+ years...and she LOVES thangles...swears by them and insisted i tried them 6 or so years ago...i did use a couple of them...but did not really 'see' the reason...my way doesn't (take me) any longer to sew...and with the thangles you have that extra step of removing the paper...so i don't get it , but i know lots of people love them, so try out what every new way you come across and decide what technique you like best :thumbup:
