Rainbow Collage Blocks

This is a time consuming project, but quite good for a half-watching TV evening.  You can do this with older children (age 5+ depending on child's attention span).

You need: as many old magazines as it takes, wallpaper paste, wooden boards in whatever size you want.  It's a good way to use offcuts you might have lying around.

Choose a colour - say, RED.  Now go through your stack of magazines and cut out everything red you see.  No need to exactly cut each shape, just cut into mosaic tile shapes.    Once you think you have enough to cover the board, paste it and start sticking on your paper tiles.  Overlap them so that no board is showing through.  It's easiest to use your hands to smooth down the paper.  You can wrap them around the sides of the board too. 

If you like, you can cut out letters to spell out the colours.  You could paint the words also with a stencil if you can't be bothered finding letters in the magazines.  You could even try a 3D version and collage wooden letters before attaching them to the board.  Lots of ways to do it.

Makes a graphic sort of rainbow for children's rooms.
