Turn an Old Six-Pane Window Into a Message Board

Clean the glass and frame well and then let dry completely. Use a window with secure glass and are true divided light panes (not a snap-in piece). Make sure the caulking around the glass is also secure. 

Seal the wood parts with the spray sealer, such as a shellac.

For the chalkboard panes, use painter’s tape along the inside edge of the wood next to the glass, then paint the glass with magnetic primer. Apply a second layer of magnetic primer, let it dry and then apply a coat of chalkboard paint over it and let that dry.

Measure the window panes that will be getting covered in cork and then cut two pieces of cork to that size.  You'll want two pieces for each pane to make it double the thickness.

Use construction adhesive to glue two of the pieces of cork together, this will give you a thicker cork board. (Sometimes it helps to place heavy books on them while the glue is drying.)

When the glue is dry, lay a piece of fabric on top of the cork and attach it with spray adhesive. Make sure there is enough fabric to wrap around the edges.

Measure the dry-erase board the same way you did the cork and cut one piece for each pane.

Spread construction adhesive onto the glass and then press the dry erase pieces and the cork pieces into place. Use something heavy like books to hold down the pieces while they dry. 

Apply a bead of clear caulk along the inside edge of the painted glass panes and the dry-erase panes to give them a finished look and help keep them in place.
