Was just going through a bin of spring stuff and came across another craft we did for moms one year. I have made some games the same way and bought some boxes of stickers come to think of it to make more that I haven't done - if anyone in Ottawa wants to come to a podgy party and trade stickers let me know.
Need: podgy(modge podge), metal juice lids, stickers of your choice (doesn't matter what is on the back of stickers or how old as you won't be activating the adhesive), peel and stick magnets
Pour a small amount of podgy into a dish or even onto a metal lid. Have child dip finger in the podgy (looks like white glue) and spread around the metal lid. Lay sticker of their choice in the middle. Carefull repeat spreading a layer of podgy on top of the sticker and especially around the edges but spread it evenly. Set aside to dry. You may want to spread another layer of podgy on once first layers are dry - especially if you are using the lids for a game. The more layers of podgy the stronger the seal. Add a magnet to the back. Colour a picture for mom on paper and send home - magnet will hold picture on the fridge.
This could also work for dads depending on the stickers used which is a good idea since dads tend to be harder to think of something for.
