Paint the canvas with several coats of paint until fully covered. Let dry.
Lay the canvas on a table and spread out the 25 boxes. Decide the layout and then take a picture with your cell phone so that you can remember where each box goes.
Choose your scrapbook papers and cut to fit the lids of the boxes using the craft knife and ruler. Set aside.
Paint the boxes with a variety of acrylic paint colors and let dry.
Decoupage the papers down to the tops of the boxes. Work one box at a time. Spread a medium layer of Mod Podge on the top of the box and then smooth down the paper thoroughly. Wipe away any Mod Podge that comes out the sides of the paper with your brush. Allow to dry for 15 - 20 minutes.
Mod Podge the lids of all of the boxes on top of the paper to seal. You can seal all the boxes too if you want. Let dry.
Paint your wood or chipboard circles with your coordinating paint colors. Let dry.
Add embellishments with craft glue, including ribbons around the edges.
Add adhesive numbers 1 - 25 on the boxes OR use a die cut machine and Mod Podge the numbers down.
Let the boxes completely dry, then glue down to the canvas. Let the canvas dry completely before using.
