This is a group for artists who often receive 'prepaid return envelopes' or postcards and wish to embellish them. These may be from catalogues, trade literature, tax or health organisations, and whatever
Instead of binning/trashing them or recycling them, turn them into artwork. Incorporate the return address, any postal franking and other text into the composition, either abstract or figurative,
You must incorporate the text and not blot it out or block it in however.
The challenge is to make it eye-catching and witty.
