Last year, I was able to make a bunch of these "sleeping bags" out of pieces of felt for my CC Community. It was an easy project which the parents and kids loved; so I've decided to share a tutorial on how to make them.
Step One: Buy several pieces of the 9 x 11 more or less rectangles of various colors of felt found in the arts and crafts section at local stores such as K-Mart and Wal-Mart. Each piece will make 2 "sleeping bags."
Step Two: Cut the felt rectangle in half long ways so that you now have two long rectangular pieces of felt.
Step 3: With a complimentary color of felt, cut out strips or wavy pieces of felt to use as a pattern on the "sleeping bag".
Step 4: Sew the complimentary colored pattern pieces onto the half piece of felt.
Step 5: Fold the half rectangle piece in half long ways with the pattern/complimentary color on the inside. Sew the edge of the bag and the bottom of the bag, leaving the top open.
Step 6: Once sewn, turn inside out. You should now have a long, thin rectangle case with a pattern on it.
Step 7: To make a cover clasp, cut a 1" x 2" strip of the complimentary color of felt. Sew this piece onto the inside top of the "sleeping bag".
Step 8: Use a seam ripper tool to cut a button hole in the top portion of the strip that you just sewed into the bag.
Step 9: Sew a button on to secure the closure flap.
Step 10: Surprise your kiddos with this cute protective case for their tin whistle.
