Once you've let the garment escape...

...resign yourself to the fact that you're never going to get it back into that stuff sac...
Same with duvets and sleeping bags... stuffing is an art form... and by nature I'm a folder...
Having read Ingeborg's journal, it does remind me of a ski trip by car with our friends' two daughters. They had been warned they could only take one cuddly because of space constraints - so the younger one borrowed a nightdress case which was itself a fluffy toy, and stuffed it with quite a few more - job done ;)
