Step 1
Sketch a thumbnail of the image you want to make in your mosaic. Shade it using large blocks of color.
Step 2
Choose an old painting with similar colors to those you selected in the thumbnail drawing.
Step 3
Use a ruler and cutting mat to measure and cut out mosaic tiles from the painting. A craft knife will give you a nice, straight cut but a pair of scissors works as well.
Step 4
Arrange the cut-out squares on to a table top or large piece of white paper. Try to arrange them by color.
Step 5
Sketch your thumbnail drawing onto a full-sized piece of paper. Map out each color section to keep the color blocks organized.
Step 6
Start laying down mosaic tiles beginning with the main subject of the mosaic. Once your happy with each block's placement glue them down.
