I was happy to make a recent discovery of
colored paper tape at my online art store. It really makes any type of mosaic work a slam dunk,
with no messy glue.
1. Beginning with 1" green tape, cut strips into squares and line up across the bottom of a sheet of black paper.
2. Use purple tape squares to make the inside curve of the rainbow.
3. Continue adding rows of blue, light green, yellow, orange and red.
4. Finish off with rows of light blue for the sky.
