After a bit of tidying up at the weekend, I found an old changing bag with a broken zip which I don't use any more. I decided to cut it up and make it into a set of 5" x 4" bellows with the help of the laser cutter we have at work.

I have already documented this on Facebook:

I know some people don't like Facebook as they think their souls will be stolen after just one visit so I will start to add some pictures here in subsequent posts.

Feel free to point, laugh and tell me where I went wrong or alternatively, post your own bellows making hints and tips.
