The paper left from last year should be in a tin in the drawers - I did them last year! I have a big pack of origami paper that I can donate.
Flextangles - I recommend using sticky tape rather than glue as the glue just takes too long and kids aren’t patient enough. I can donate a load of rolls of that too ( somehow I have a drawer of sticky tape at home and I can’t even remember where it all came from). I suspect I am the God of Sticky Tape and these rolls have made a pilgrimage to me.
@Giles found a large roll of gift wrap paper yesterday - he kindly donated it to the community. It’s in the messy room. At a wild guess there may be 100m or so - certainly enough, if the paper is suitable for what you want. I’ll be in later today and will put it by the sublimation printer.
Just to be clear, I found it some time ago and it has been around for a while.
I myself used it for wrapping a couple of parcels recently. It has numerous uses. All good.
