Steal a few filters from the coffee machine and fill an empty wall with a spray of mod blooms.
To make each flower, trace cans in two or three sizes onto colored card stock.
Cut out the circles, then stack two or three in a coffee filter. Attach the flower to the wall with a thumbtack. (If you'd rather not make holes, use repositionable glue dots between layers and to hang the flower.)
Repeat to create your desired floral arrangement.
