Allow me a moment of lead up...I took on a rush job. Stupid, stupid, stupid...I'm swamped. So, it's promised for tomorrow AM, frame arrives at 2:30. Busy, busy, busy all afternoon. Double opening in a double mat. two different color mats in the bottom reveals. No time to get to it by closing. Husband hurt his back at work, got to get home with dinner. No problem...I'll fly to the local farmstand. Head home, remember I have to provide snack for daughter's class tomorrow. And there is a field trip I am driving for. Head back to town to buy supplies for the yogurt sundaes I promised daughter we would make. Get home, do dinner, assemble 36 individual yogurt and fresh fruit sundaes. Get daughter settled and off to sleep, then head back to work for 10pm. Finish a few small projects to warm up before diving into rush job. Mat cutting does not go well. After third attempt, have a very nearly perfect mat...except for one small problem. Lots of small black marks showing on bevel of one of bottom mats. Pencil lines? nooooooo....the printing on the back of the artcare board that indicates the color # is running directly along the bevel line! Back to the drawing board. Will I think twice before I accept another rush job when I'm already too busy? probably not.
