Step 1: Take some digital photos. Put them on Flickr if you like.
Step 2: Go to moo.com and use your photos (imported from Flickr or uploaded or whatever) to design a box of 100 Minicards. I did 10 designs x 10 cards each, but you can have 100 different ones or all the same or any ratio you like.
Step 3: Put your contact details on the back as part of the design. Then order the cards. They cost £9.99 for a box of 100. Here are mine.
Step 4: Go to Muji – either in store or online – and buy a “Portable Ashtray” for £2.95. Here is mine.
Step 5: Wait for your cards to arrive, then put a few in the ashtray, which you will be overjoyed to discover is the perfect size. (Moo Minicards are an odd size and not at all compatible with regular business card holders). Here are mine.
Step 6: Bask in the wanton adoration of all around you.
