Things You'll Need
Instructions
Lay the flannel right-side-down on a flat surface.
Center the foam core board on the flannel.
Run a line of glue down one long side of the board, 1/2 inch from the edge. Stop 1 inch from each corner.
Fold the edge of the flannel over the edge of the board, onto the glue. Glue down the opposite side in the same way; stretch the flannel tightly.
Glue down the other two sides in the same way.
Cut off the corners of the flannel ,1/2 inch from the point. Fold in each corner at a 45-degree angle. Glue down the folded edges on the back of the board. The folded edges should just touch each other, forming a mitered corner.
Glue 1-inch strips of felt on the back of the pictures you wish to place on the board. Cut shapes from felt to place on the board.
