I use straight of grain binding unless I am doing curves OR if I want the barber pole effect of strips or plaid on the edges. I usually use a full square of fabric that is the same length as it is wide. I use my large ruler to draw a line from one corner to the opposite corner on the 45*. This is the longest bias strip I can get. I measure over from the first line 2-1/4 inches and draw a line and so on. I still have to join the ends when all my strips are cut and I put the smaller lengths between the longer ones. I have tried doing the continous tube bias binding but it was more trouble then it was worth.
