Just thought I'd share this with you.
I cant really afford a new sleeping bag so I decided to make a homemade version, I took a very cheap second hand sleeping bag (cost £7.55 inc postage) off ebay, bought a double duvet (£12) from Woolworths, carefully unstitched the bag and refilled it with cut up pieces of the duvet. Have had to modify it slightly as I found that parts of the bag were glued together. All told I tried the bag out on Dartmoor last weekend and it seems slightly too warm for me so far. Just thought the idea might interest some of you on here who are on a limited budget and need a way to increase the rating of your bag.
