Old camping mats (Roseburn EH12)

2 Therm-a-Rest inflatable sleeping mats, size 51cm x 119cm. These are quite old and they both leak. We don't need them any more and rather than just throw them out, I thought I'd offer them here in case someone else wants to have a go at fixing them. (There's lots of advice online about how to do this: seam sealer/other glue, duct tape, patches, or even the Therm-a-Rest repair service.)
