Try one border material and alternate it with a solid (or tone-on-tone) instead of another border. If using a solid, remember, you won't have to fussy-cut it. Just use 4 7/8 HST's with 5 1/4 QST's.
Or use one border, but find two different starting cuts for the two pair of cards. Quilt Mom is right. You may be pleased with what you create.
Show us what you have, klgreene!
