If you are using sticky-back felt and googly eyes for your decorative pieces, stick them on after you have sewn the body of your costume.

If you are using regular felt for your feature pieces (wings, eyes, beak), you will need to sew these on before sewing the main body.

Lay out your felt features on top of the front body piece of your costume (the one with the square hole). Make sure you don’t cover up the hole for the LED grid and you should leave a space around the edge of the front body piece for sewing to the back body piece.

Take some thread and tie a double knot in one end, then thread the other end through your sewing needle. Hold one of the feature pieces to the body front and then push the needle up through the two pieces from the underside of the front body piece (not the decorative side). Pull the thread through until the knot and then push the needle down through the two layers a little distance along the edge of the piece. Repeat this around the whole edge of the piece, then tie a knot on the underside of the body front and cut off the remaining thread.

Repeat this for each felt feature piece.

Lay your body front piece (with the decorative side up) on top of your body back piece.

If you want to power your CodeBug using USB then you will leave need to leave a gap at the top of the costume by making two stitch lines as shown below in the owl on the right.

Tie a double knot in your thread and thread your needle again. Hold the two body pieces together and push the needle through the back piece from the inside of the body to the outside, near the bottom of the costume (make sure you leave enough room to slide in CodeBug by placing it). Pull the thread through until the knot, then push the needle up through the two layers a little distance along the edge of the piece. Repeat this around the whole edge of the body, then tie a knot on the underside of the body front and cut off the remaining thread.

Then slide CodeBug into your costume.
