Punch out several polka dots from the papers and swatches.

Arrange the dots on the wood canvas board and take a pic using your cell phone (so you can remember where things go).

Transfer the circles to a separate surface.

Mod Podge the dots on the back and then press onto the board. Continue until the board is covered and let dry for 15 - 20 minutes.

Add the second layer of dots with Mod Podge (for those you want to apply a second layer) and let dry.

Cover the entire wood canvas with decoupage medium and let dry completely.
