I first noticed this lovely little fold nestled amongst the masterpiece that is Eric Joisel’s Musicians, and decided that i must try to work out how to make it:
Presenting a tantalising hand-drawn crease pattern idea on his memorial website, I decided to try and work out a method for this fold.
Unlike the original, my design is based on a 32 x 20 grid, making an extra gather in the bellows section (which is not a bad thing) and a simpler join along the long seam (which, sadly, I still needed to use double-sided tape to close).
The geometry of this model is really nice – the bellows almost fold themselves when the creases are laid in – I experimented with the seam in and thought it looked better with the strappy seams out in the bellows.
On the same hand-drawn crease pattern, there is another that supposedly makes a saxophone – might give that a whirl as I seem to be in a musical instrument frame of mind at the moment. very happy with this one however, and need to move on from it.
