These simple heart sun catchers are so easy for young children to make, and they look so pretty stuck up in the window as a sweet Valentine's Day decoration. All you need is some thin coloured card, some clear contact paper (sticky backed plastic) and some collage materials, we used torn up red and pink tissue paper. I used my Cricut Mini to cut out the heart shapes. There is a basic heart shape supplied in the cartridges that come with the machine, and when I logged in this time I had a free trial of the Love Struck 2010 cartridge which is where the slanted heart shapes came from (although you could recreate this shape by manipulating the free basic heart shape). Of course it is also easy enough to cut out a heart frame using scissors.
