What you needwhite paper glue
clear plastic film
Start by mixing a few drops of coloring to the white glue and stir it well. If you want more then one color then make little tubs up using different food colors.
Draw a design onto paper or use a coloring book picture.
Now put your design under the clear film and trace over it with a continuous bead of glue and then fill in the inside of the pattern making one big glue picture.
Let it dry for at least half a day then peel your project off the plastic.
Stick it up on some glass or on a mirror.
NOTE: Do not place them directly into sunlight or heat as the glue will become tacky again.
