I love to cut fancy borders out of 12x12, then glue the middle in with a coordinating paper or cs. I did one with little musical notes cut out all over the border that was cut out. It took the Cricut (my 1st cutter) a long time to cut all those little notes out, but totally worth it!
Doing the border in one big piece makes the corners nice and neat. You can also make the pretty overlays that are so expensive to buy. I'd go for the 12x12...but that's the only size of scrapping I've done so far.~Judy
