A simple set of a front piece with a window and a flat back (both with a hole for hanging). Laser cut from medium-weight chipboard.
Plus an extra piece with a scalloped edge. You could turn this into 2 ornaments or one that is double-sided (if you use the scalloped-edge piece sandwiched between the other 2, you'll have a fancy edge showing outside the front-most pieces on both sides).
Bonus: see the extras photos for 2 tips: Even the largest layer is sized so you can cover it with a sheet of paper from a 6x6 paper pad (the Vintage Christmas 6x6 Paper Pad is shown in this example). AND: the window cut in the front chipboard layer also fits the Clear Plastic Round Domes (in case you want to turn the ornament into a shaker card). Clear Plastic Round Domes sold separately.
This ornament is also included in the Ornament Frame Set Kit; see all the other kit components.
