Mine ended up being very simple - to many grumpy kids this week to cooperate for hand tracing and such the craft needed. Instead we made a suncatcher in a frame. Got the idea from a card shared on a facebook page where they had done a heart and let child tear pieces of paper to put in the heart and the caption read Mom: I love you to pieces.
I gave each one a piece of contact paper sticky side up and a dish of tissue pieces. They placed them where they wanted and then I covered it with another piece of contact paper to create the suncatcher part. Then I had cut a frame from pink cardstock leaving a rounded part in upper left and bottom right corners - 2 per child. Then taped insert to one page, glued around edges using tacky glue and laid on top frame. I printed tags from the computer with the Mom to pieces phrase and cut them out using shaped scissors so they looked jaggedy. That went in the upper left rounded spot and I had some butterflies I had diecut from the cuttlebug and one of those went down in the bottom round spot. I put their names and year on the back. Simple, their part done fairly quickly although they enjoyed it and the assembly done by me during naptime. But as they finished we taped them to the kitchen window so they got to see the stainedglass effect and were suitably impressed. Even the baby who is 12 months old got to make one. Helped him put two pieces on then left him. He picked up the dish of pieces and in the process of playing with the lid dumped the pieces out onto the sticky mat which I then grabbed and sealed it up - got what I needed and he got to play with the lid so his design is more of mass in the middle but still the overlaps look nice. 2 moms and 3 dads picked up. Regardless kids were pleased but really for something so simple it was a lot of work which is why we do more games and activities with things I have made then actual crafts.
