Are they paper or card? If stiff enough they could be used in
pairs for making woolly bobbles. You put two identical shapes
back to back, wrap the wool through the central hole and around
them until you have enough on, then insert your scissors between
the two sheets cutting the wool , which you secure round the
middle, then fluff it up to a ball shape.

....so, you clearly spend a lot of time making fluffy bobbles, Chris?!
