Was pondering the crappy weather at the moment and trying not to dread our camping debut later on this summer 
, and wondering about how to insulate our tent from the cold ground. We have these from an NCT sale (never used them with DC actually - I bought them to stretch knitting on while blocking! 
) and I wondered if there's a reason why I shouldn't lay some of the squares out in the sleeping area and put our SIMs on top? Nice insulating foam: also soft and bouncy underfoot. Can be more or less shaped to most areas. Has anyone else tried them in tents?
Of course, there's the small matter of them taking up a hefty wedge of space in the car... I think I'm in denial about what we can fit in there, TBH.
