It's a bit of a challenge to glue on the two back pieces so made a one piece back and added a Star so it pops a little more. On the silhouette we turned the star over (bottom of the cut showing) just to give it a bit more depth. This was done on D1pro 5w - I can fit 9 on a 12x12 sheet.
Using grid arrange the current size allows you to put 9 on a 12x12 board. I do 9 front on a board then 9 backs on a second cut. Stars stack fine between the ornaments.
See above settings my 5w uses to cut these out.
