This faux tissue box get well card is a favorite of mine because it is so easy to make. It also folds flat for mailing. When people see it they get excited and note that you could fit one of those mini packets of tissues in them. Ah.... but then it wouldn't lay flat for mailing.
This one does because it is just a few sheets of buns' wipe* tucked in there.
*Buns' wipe also known as loo roll, bum wad, arsewipe, ass napkins, toilet roll, TP or toilet paper; formerly known as last year's Sears and Roebuck catalog. The Fine Print: Stamp by Hambo Stamps.
