My refrigerator was becoming cluttered with all my nephew and Alvarez kids pictures + the postcards of missionaries I support/pray for. So I came up with the idea of segregating the missionary pictures. I bought a small bulletin board and hung it in my kitchen. I used a piece of ribbon to separate missionaries and prayer requests.
All the missionary postcards are at the top; I use the bottom of the bulletin board to post prayer requests. I just cut some index cards and hand-wrote those and keep a few blank cards in the corner to add new prayer requests. Some of the prayer requests are from blog land - Heather, Kelli, Ethan, and Cameron.
The remainder are church-related, though my church does publish a prayer/praise list on Sundays and Wednesdays, so I use that, too.
This works for me!
