What's a mosaic? It's a picture crafted with lots of small tiles -- or in this case, paper squares.
Before you design your mosaic, look at old mosaics in books or online for inspiration.
Sketch a design on the back of a paper plate; we chose a sun pattern.
Tear out magazine pages printed with shades of the colors you'd like to use. Cut strips of the pages into small squares (ours were about 3/8 inch on a side). The shapes don't have to be perfect -- a little variety is what makes a mosaic interesting. You'll also need a few triangles to fit in corners.
Mix together equal parts white glue and water. To fill in the design, brush a bit of glue mixture on the plate, put the squares in place, and seal each with a top coat of the glue mixture. When you are finished, let the project dry completely.
