My scrap pile from card making was getting wildly out of control. So when I came across a few samples on pinterest I loved that looked like they would put those scraps to good use, I set up a mass production system on my workspace.
My first card was one that used various sized squares and rectangles, including a background mat that could have detail in one corner. I can always use a stash of "generic" cards. So I pre-stamped seven penants of each sentiment (get well, good luck, celebrate and thank you) to have on hand so I can grab them, adhere them, print a pertinent inside and run out the door =) I went a little crazy weeding out any scraps that coordinated and were in the right dimensions. I did TEN takes on that one!
Card dimensions: 4.5" x 6.25"
Mat: 4.25" x 6"
Top rectangle: 2" x 1.5"
Bottom left rectangle: 2" x 4"
Bottom right square: 2" x 2"
Other supplies: scrap ribbon, misc buttons
