Little Jams tombola

The concept of "tombola" was new to me until not too long ago-- and this pic from Waitrose Food magazine shows how it works. You need prizes and a book of cloakroom tickets - the actual tombola barrel is optional, but a nice touch. The prizes get tickets stuck on them, with numbers ending in 0 or 5 - and tickets with numbers from 0 to 9 go into the barrel. So drawing a ticket out of the barrel has a 1 in 5 chance of winning.

You could say that "Little Gems" are appetisers for making bigger quilts? Or, if you make enough of them, satisfying in themselves?
