How to Build a Flag Case

Item(s) have been added to cart.

Measure and Mark
A man uses a pencil and measuring tape to measure and mark wood.
  • Gather all of your materials. 
  • Now, measure and mark cuts on the 1-inch x 4-inch x 8-foot common board according to the cut list.
Consult the Cut List
A cut diagram illustrates how to cut wood.

Follow the above cut list and diagrams for reference as you cut plywood and assemble your flag case. 

Cut the Wood
A person uses a circular saw to cut wood.
  • Use a circular saw to make the straight cuts on the common board.
  • Use a miter saw to cut 45-degree angles into one end of the two shortest boards and both ends of the longest board.
Make the Front and Back of the Case
A circular saw is used to cut the triangle shape.
  • Assemble the common boards into a triangle shape and trace the profile onto the plywood twice (once for the lid, once for the base).
  • Trace the inside of the triangle shape onto the polycarbonate.
  • Use the circular saw to make straight cuts on the plywood. For the lid, measure 1 1/2 inches in on each side from one of the plywood pieces.
  • Drill a hole for the jig saw on the inside of the traced section.
  • Use a jig saw to cut the interior triangle shape from the lid.
  • Score the polycarbonate with a knife before snapping over the edge of a table.
  • Use a sanding block to smooth any rough edges.
Stain or Paint Boards
A man stains the boards.
  • Stain or paint boards prior to assembly, if desired.
  • Allow time to dry completely.
Assemble the Case
A man assembles the case.
  • Build a triangle out of the boards, as shown in diagram above, and secure with a brad nailer (trace the frame onto the plywood to get exact profile for cutting).
  • Place the lid on top of the triangle and secure with brad nails.
  • Insert polycarbonate inside the box on the lip of the lid.
  • Secure with double-sided tape.
  • Place folded flag in the box.
Attach the Case Back
The case back is attached to the wood.
  • Place the back on top of the case and pre-drill a 1/8-inch hole in each corner of the plywood and case.
  • Screw the back onto the case (screws are used so that the folded flag can be easily removed if necessary).

Use this case to display a folded American flag anywhere, whether on a shelf or desk, or hanging from the wall. It also makes a beautiful and thoughtful gift for a veteran or military family. The Home Depot is your DIY headquarters. Looking for a product to complete your project?
