This drawing was inspired by walks with my children in Epping forest, I've printed it onto 100% recycled card and it comes with a white envelope.
the card is A6 in size (105mm x 148mm) (4-1/8 x 5-7/8 inches)
My greetings cards are posted out wrapped in biodegradable, compostable wrappers, in hard backed, recycled envelopes.
