You can create a simple saxophone using a single square of paper (standard origami paper or a 15x15cm square).

: Fold the outer edges into the center crease to divide the paper into quarters.

To create an alto saxophone from paper, you can follow an origami approach to fold a miniature version or use a template to construct a larger 3D model.

: Fold the paper in half lengthwise so the house folds are on the inside. The Mouthpiece & Bell : Fold one end at a 90-degree angle to create the bell. Fold the opposite end slightly to represent the mouthpiece.

: This is the trickiest part. Take the corners of the top squares and perform a "house fold" (folding them down to look like a rooftop).
