I've always used the offset way of sewing the seams of the rectangle (once the triangle has been cut from one end, and applied to the other), but I like Bonnie Hunter's way of getting the TRUE bias. I think it would be faster in the long run too. Thanks, katier825!

The method I use is very similar to Bonnie's.

On your already-cut-wrong-direction striped binding, can you put all the left handed together, the right handed together, and make the direction change hit at opposite corners?

what I do is exactly what Bonnie Hunter does - that is the way I learned to make yards and yards of bias for cording trim for furniture. BTw - if you want stripes to all lean the same way (and not change direction at corners) you do have to cut some the other way, so you want to start with two rectangles (one for each) and have the angles going opposite each other.

I have tried binding ends for so long that I'm just about to give up. Then I clicked on this link and it's the best one I ever saw. It all makes sense now. Thank you, Kris, for that link.

Georgia Bonesteel (from many years ago) had a method for continuous binding. I use it exclusively. Have never tried to Google her, since I have her books. Something to try.

This is what I did. First I thought I'd just buy more fabric cut it the same way and get two lots of right slanted & two lots of left slanted binding. Of course there was no more of that fabric left. I didn't really want all of that binding. Probably only the quilting police will notice. Sadly she takes care of our donation quilts.
Will check out that Bonnie Hunter link.
