I'm doing my bit for Cancer Research UK.
All you have to do is craft an A6 card, any theme, using products of your choice and leave the inside blank. Then pop down to your local Cancer Research shop and pick up a few of their special cello bags. Pop in your finished card then either sell to friends and family for £1 or give back to the shops to re-sell. Every little helps!! Why not join in....
I've done 3 cards already and working on another 3 - then they'll be taken back to the shop for them to re-sell for £1 each. I may even pick up some more cello bags and make more!
