Measure and mark cuts on the 1- x 4-inch x 8-foot common board according to the cut list.

Consult the Cut List
cut diagram

Use the cut list and diagrams for reference on all remaining steps.

Cut the 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

  • 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
stain/paint boards
  • Stain or paint boards prior to assembly, if desired.
  • Allow time to dry completely.
Assemble the Case
assemble case
  • Build triangle out of boards as shown in diagram above and secure with brad nailer (trace frame onto plywood to get exact profile for cutting).
  • Place lid on top of triangle and secure with brad nails.
  • Insert polycarbonate inside box on the lip of the lid.
  • Secure with double-sided tape.
  • Place folded flag in box.
Attach the Case Back
attach back
  • Place back on top of case and pre-drill a 1/8-inch hole in each corner of plywood and case.
  • Screw back onto case (screws are used so that folded flag can be easily removed if necessary).

This simple DIY project will give you step-by-step instructions on how to build a beautiful flag case with a unique design. 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.
