Question about mitered corners on borders
Is there a rule of thumb about how much extra fabric you leave on borders to make miter corners? I am thinking of making them on a top that may have 6 different border strips. It seems like it would easeier to sew stips together and then sew them on the quilt which means the corners need to be mitered. I have watched videos suggested by others so I think I know how to make them but need to know how much extra fabric to leave. Thanks for you help!
