It is a fun technique and you should really try it. I do recommend you mark which side goes with which side. I did get confused once I mounted my pieces on the dark matting but I think I got them all matching up.
This will be it for the month of January. I made a total of 11 cards. Used at least 9 of my stamps or stamp sets, some punches, different inks, jewels, embossing powder, glitter, a rub-on and other embellishments. I did not have to go out and buy anything so I am pretty proud of myself.
