I wrote about angrychicken's mailorder club quite a bit ago. I was able to secure a subscription, though they sold out fast. It was soooo fun when it came. I love it. The creator, Amy Karol, did a great job. She has a fun sense of humor and of course, a love of paper. She has even started a "very official mailorder group on flickr" where people show what they have made.
Here is my finished paper project for March, a birthday calendar. Maybe I really will get better at remembering birthdays now. Below is what I made up to hold all the other mailorder goodness like mailorder money, official club member card, merit badge plaque, recipe card, postcard, etc. etc. It's not too late to sign up for the second month if a simple paper project sounds fun to you!
