I just learned about this AWESOME idea from Monica over at Happy Zombie. She has created a beautiful quilted pocket to collect money to send to Japan. The idea is to make 2 pockets. One to keep at your house and collect money (spare dollars in your pocket as you walk by, swear jar, etc). The second you sale and donate the proceeds to a group helping out (Red Cross, Mercy Corp, Soldiers' Angels, ShelterBox, etc.).
So head on over to Happy Zombie's blog and grab the pattern and make some!
