I use scraps for binding alot & like the look of the diagonial seam.

It depends on the quilt you are binding. Pieces joined end to end look good if they stay no longer than 6 1/2-inches. Perhaps would look even better at 4-inches. A serious and/or formal quilt would not be a great candidate but a really scrappy quilt or 30's repro fabrics would look very cute. If you use the pieces joined on the diagonal it would look good on a diamond pattern quilt or something in batiks.

I cut my strips (various lengths) and chain-pinned them. I LOVE the mix of colors - I had 5 minutes to start sewing, then had to leave for work. Now I'm stuck in the store because of the blizzard! C'mon boys and get those plows out - Mama's gotta get home to her quilt! :)

if you start with 10 inch wide fabric, sew the diagonal and then cut these into 2.5 inch strips you will same a lot of diagonal sewing - which might waste some fabric, but you did start with scraps.

I like the diagonal seams, but I don't think it matters a hoot

I agree....six inches is too short. I just barely sewed a scrapy binding on a baby quilt. They were about 14 inches. I love scrapy binding.

I prefer the diagonal seam.

And less likely to split, as a weak point.

I think diagonal seams look best.

Definitely join them at a 45 degree, because you will get too much build up where both seams meet.
