Rainbow Heart Shadow Box Supplies


  • 12 x 12” Lucius White Frame
  • Cardstock of various colors
  • Ruler
  • Glue Pen
  • Popsicle Stick or Bone Folder
  • Optional: Heart paper punch or Cricut cutting machine

This project can be made using traditional scissors, a paper punch, or using a Cricut cutting machine to cut out the shapes. Whichever route you choose, do your best to keep the shapes the same, especially when applying the second layer of shapes in a later step.

Cut Out Rainbow Hearts

First, cut hearts from colorful cardstock.  You can go the traditional rainbow route, try a pastel rainbow or try an alternative bright rainbow palette, as seen here.  Our 12 x 12” Lucius shadowbox uses (10) of each of the (6) colors shown.

Line Up Rainbow Hearts

Glue Rainbow Hearts

Get your ROYGBIV on and lay your paper hearts in order on the smooth, white shadowbox backing. Use a glue pen to adhere the shapes to the surface. Tip: use a ruler to help line these up as best you can.


Fold Rainbow Hearts

Lay a ruler on the center of your heart shape and run a bone folder or popsicle stick along the edge to score it down the middle. Fold the heart and rub along the crease with the flat part of the bone folder or popsicle stick for a crisp crease.

Rainbow Hearts Shadow Box Complete

Unfold and apply glue to stick on select hearts for a dimensional look.
