Are you familiar with Operation Write Home?
OWH is a wonderful group of folks who send homemade cards to our service people - for them to send home to their loved ones.. They are so thrilled to be able to get something to send for birthdays and holidays. Right now they have a big drive on collecting Valentine Cards. You can read about it here http://www.owhstarsandstamps.org/2010/11/welcome-to-be-my-valentine-bloghop.html
The Blog Hop will take you to many, many blogs of people who participate in this project. They have shippers and people and companies who donate shipping costs - it's quite an operation.
The gal at this blog,
is offering 'candy' (mostly stamping goodies) for people who participate.
Check them out and do what you can. It's so worthwhile.
