I believe all the BOMs I am currently working on are on a site called "The Goldeen Thimble". When you get to the website, click on The Quilting Clubhouse, the scroll down to the calendar. Each day has a different free BOM.
I am working on:
Henryetta Whiskers-5th of month
Grannys Hankies 2nd St of Mo
Garden Party - 3rd Sat of mo
My Tweets - don't know date available
Hearts Desire - around the 15th
CrazyCats - ?
Fiesta - 3rd of mo
I am also working one from a LQS called Graceful Baltimore and getting ready to start working on Jinny Beyer's Summer Lillies. The pattern for Summer Lillies is free right now. Go to her website - JinnyBeyerDesign.com to find the pattern. I have posted pictures of some of these already.
