As you can imagine, this has the possibility of getting very expensive so I'm always looking for cheap, free or recycled things to use. I came across these sun catchers on Crafster. (would love to link, but there are at least a dozen contributors to the 2 different threads) They are simple and the kids can help with part! All you need are pony beads, an oven and a baking pan.
Simply place the beads in the pan.....my son arranged his into a rainbow for his step moms Mothers Day present (sorry, forgot to get the picture out of his ipod...will add later!) No cooking spray or oiling needed. Bake at 400degrees for about 20 minutes. Let cool and the sun catcher will pop right out. Simply drill a hole and hang. You might even be able to skip the drill part if you left a gap between a few beads. That's it!
I also used a mini bunt pan to make mini sun catchers. I hung them from a 'natural' stick in a sort of wind-chime formation. I used pony beads that I had left over from other projects, but bulk pony beads are pretty cheap if you need to buy new. I'm planning on making a red white & blue one, and Hubby wants one with a smiley face on it. The woods are looking fancier already!
