The book I have shows the border strips being , what I think is mitered before adding to the top. It show the strips at 90 degrees angle then sew them together? I have been looking for a tutorial or pic in the search engine. Everything is geared towards mitering corners when added to the top. My top is done except for the borders . :shock:

If you mean piecing short strips when you need a longer one, a lot of people like to use a diagonal seam which would involve putting them at right angles and sewing a diagonal seam. What I use depends on the print of the fabric-sometimes I piece diagonally and sometimes straight.

If you mean borders that are mitered at the corners of the quilt, then you don't do the mitering until after you've sewn them to the sides of the quilt. If this is what you mean, I believe there's a good tutorial in the tutorials section of the board.

I am taking short strips to make a loner strip.

Excellent tutorial http://www.quiltingboard.com/t-21057-1.htm

Hmmm, not exactly sure what your question is. Do you want info on how to miter a border? Here's a tutorial:

If you want to join shorter pieces to make a longer strip here is a link that actually is about binding, but the first few photos show how to join strips using a diagonal seam.

i do sew pieces together on the diagonal making longer border pieces. When i get to the corners, i do not miter the corners.

It depends, for me anyway, on the print. If it's something like a solid, tone on tone, blender, etc I will use a diagonal seam. If it's a stripe, plaid, or big print, I might use a straight seam because a diagonal makes it more noticeable to me. I'm just anal enough to try to match up patterns and stripes and such, especially on something as big as a border. Probably leftover from when I made apparel.

That's not called mitreing. That is still piecing, but at an angle to disguise the join. Here is a Youtube video I found:

I have cut strips for the border . I need to sew them together end to end to make them long enough. I was wanting to try and miter the strips together before sewing to the top. Guess I will tinker with it awhile.

The Youtube video I posted shows how to do that.
