Step 2
Cut the linen and cotton fabric down to 8-1/2″ x 11″ (use a piece of US letter size paper as a guide).

On each piece, mark the center of the top and each side 2-1/2″ down from the top. Use a ruler to make a line from the center to each of the side markings and then trim off the corners. Each piece should now look like a house shape.

Step 4
Peel the paper backing off the stamp and iron it in place in the top corner of the center section of the envelope. It should be at least 1/2″ from the edge.

The stamp may cover part of the postmark tracing, but you can redraw that so it’s pretty close to the pattern.
