"Question: What is a Scrapling?
Crafters come up with all sorts of cool names for little bits of paper (such as the inchies, twinchie, and rinchie trio). Scrapling is another such term.
Answer: A quarter-size greeting card is typically 5.5 x 4.25 inches (the folded size). To make it into a square card, some crafters would cut 1.25 inches off the bottom. That little scrap of paper became known as ascrapling. Instead of throwing it away (it is usually very pretty, decorative paper), it is often used to craft mini cards, tags, and labels."
I see that the origin is none other than Hero Arts, here.
