Its an idea that Tammy runs through June and July, you get a stack of 3 x 5 index cards and have them on your desk then each day you make a minature work of art on them. At the end if you manage to keep up you should have 61 little cards all decorated. Here is the link to Tammy's fab blog Daisy Yellow where you can find all the information. Tammy does provide some themes and prompts but you can just do your own thing.
I was late to the party as I had to get my hands on a pack of the cards but have worked away in the evenings in the latter half of the week and have managed to play catch up
Here's my cards for week 1. I have to say I have really enjoyed just sitting at my desk in the evening playing around to see what I can come up with.
