I've been mailing these quick, improvised, hand-drawn doodled envelopes out to random Instagram followers. I'll be doing more of them so follow me @doodlers and let's be friends.
This was so enjoyable to do. Hand drawn using black 0.03, 0.05 and 0.1 fine liners on A4 medium cartridge paper. 22.5 hours of work and made my eyes hurt!
