I thought of Twodogs immediately, but its not entirely fair to ask for blankets at 9pm on a Wednesday for delivery first thing on a Friday.
I shall hunt around the charity shops tomorrow all being well, see what I can find. If all else fails I'll be sleeping in a rather horrid sleeping bag this weekend... unless I take a duvet. Not sure my better half will be impressed, but I want a comfy weekend in the woods. I've even considered going to ground rather than swinging from the trees, I desperately need a nice night in the woods.
