I cut bias 2 1/4" if it is for a scalloped or curved corner quilt, otherwise mostly 2 1/2" WOF, unless I have enough for lengthwise. I sew the edges on the bias for one long strip and iron in half. I then apply it to the back of the quilt at about 3/8", fold over to the front and machine stitch next to the folded edge with a straight stitch, adjusting my sewing machine needle to the right and using my blind hem foot with the guide down the middle. I use the point of my seam ripper to hold the fold over to the guide while I am sewing. I do this with all but my show quilts as most of my quilts are given away and I expect to be used or drug on the floor by a child.
