I made this mailbag and mail for the grandchildren to play with, and they have enjoyed it. I found the backpack at a second hand store and sewed the word MAIL and star buttons on it. The cards and postcards are made of felt, also the envelopes. I did double the felt on the cards to make them more durable, and I sewed around the edges with a blanket stitch. I used felt pieces and embroidery to make the designs, and google sew-on eyes for the eyes. The patterns and inside messages appear below.
