Hi everyone. I recently managed to buy a large sheet of 3mm Evazote foam from an online footbed company. It's wide enough for 2 mattresses, but not long enough. is it possible to join 2 pieces together? Any suggestions welcome! happy trekking everyone...;)

Many types of tape work well with CCF. Duct tape and cuben tape are options, depending on how much weight/cost you are willing to put up with. Spinakker tape might be a compromise between the two.

You could try just gluing a butt joint with impact adhesive, probably would need 3+ hands to get a tidy joint (un-wrinkled) & do it on a sheet of polythene so you don't stick it to the floor.
25mm wide spinnaker tape (cut down 50mm) either side would probably also work & keep the weight down.
