This is a simple Valentine we made for MK's class. The hardest part was finding the heart cookie cutters. Randomly, I found them at our local Food Kitty at only 5 for $1!!

I had these stickers printed from Vista Print. A sheet of 24 was about $2.25. I get stickers printed from them from time-to-time with my kid's names on them. We used them on school folders, tupperware, etc. I thought some Valentine one's would be cute for this, but you could easily use plain stickers.
There's really not much to this, just assemble as such.
