Homemade Christmas: Fabric Game

Here's a DIY tic-tac-toe game out of fabric and felt!  This was a little gift for the nephew and niece.  I don't have a great tutorial, but here's a winging-it version:

Materials:
1 30"x30" square of blue felt
4 2"x30" strips of white felt
1 20"x20" square of red felt
1 20"x20" of brown felt
1 yard of fabric
2 6"x6" squares of cardboard
Thread, scissors, and sewing machine

For the tic-tac-toe board:
-Lay the blue felt on the fabric and trim back fabric to 2 inches all around.
-Lay the white strips on top in a tic-tac-toe board fashion, and sew through all layers (white, blue, fabric).
-Iron the fabric down 1/2" all around.  Fold it up over the edges of the blue square, and zig-zag stitch it all around to finish the edges.

For the letters:
-Cut an "x" and an "o" from the 6-inch squares of cardboard.  Trace around the letters to make 5 x's on the brown felt and 5 o's onto the red felt.
-Layer the felt on the leftover fabric.  Sew around the traced letters through all layers, then cut out the letters.
