This quilt went together fairly quick even though I had some problems with the inset triangles. After EQ 7 failing to allow me to have full sashing squares at the border. I went out and bought this calculator with a Joanns coupon 40% off! Great buy! It basically does all that EQ can to but I can stick it in my purse and never has to ask the sales gal again how much fabric I need. And it can figure out those quilting math problems that sometimes take me hours.
