I cut them on the straight, but join them on an angle.

Holice caught the "Joining the PIECES in a border - - "

I also prefer to join them diagonally. I think it usually looks better and the seam seems to disappear - but if the fabric design says otherwise or if I'm limited - I'll do a straight join.

Sewing the pieces together on the diagonal makes for a less bulky seam. I recently did a baby quilt and ran out of material so I had to join with straight across seams. Didn't like it and had to do some manipulating of the seams when I hand stitched it down.

I do all of my borders straight or pieced.

If you are going to enter a quilt into a show for judging check on what the judges have said in the past. Usually the cut straight but joined on the diagonal gets more points. Or so I have been told.

Yes, JOINING (not cutting) the border strips on the diagonal almost always looks better to me, although there some fabrics where a straight join looks better. I like the way the diagonal join causes less bulk, too.

Most of the time I join diagonial unless I am short on fabric then I will do straight since it takes less fabric. If I join straight then I try to match border seam with seam in the inside so it is less noticable.

I also do mine straight.

I cut them all on the straight only.

I usually do bias. I think it makes the binding stronger. I always double layer it, too,
