We are family of five in a 6 berth caravan with bikes and all the kit that goes with it. I'm sick of shifting stuff so this year I am on a mission to shrink things! So far I have compact duvet for DH and I, small chairs for the beach and replaced all normal towels with those microtowels which are actually amazing! We've hardly bought any clothes which has been good and I have improved our use of storage with mesh bags and taking out pointless crap.
Anything else anyone has done to shrink?
