Well if the accordion is jammed I have a lovely Swiss Army Melodeon Repair kit here.... knife to fix the bellows, screwdriver if that fails, and if that doesn't work, a toothpick to poke the operator in the eye!

If it's accordion jam - it can't be as nice as Mudguards' 'moosberry' jam he bought me last year (and is wonderful on cranberry bread) and is nearly finished.....

If it's the paper sort, well, you've got the beginnings of a DIY paper lantern factory and I'd investigate the effect with other types of decorative paper....
