It is possible to cut inner tubes and seal the cut ends. This gives you more layout options and means you can inflate an outer 3-sided tube separately from the complete inner one - a bit like the original.
After cutting to length clean the inside of the tube with thinners and run super glue around the inside. Clamp together for a couple of minutes (I used a couple of small wooden battens and a G-clamp) and you'll have a permanent airtight seal.
I made mine about 4 years ago and they've never needed re-inflating.
Car inner tubes are a bit thick and some thought has to be given to the position of any folds so they don't create lumps and bumps.
