This is NOT just a "Sentimental Stitches" BOM.
This project is by both Gay at Sentimental Stitches and Brenda at Dear Jane. There are multiple blocks every month. On the 1st of each month Gay will post blocks on her blog; on the 15th of each month Brenda will post blocks on her site. For this reason, it is best to always start at the "Just Takes 2" blog, which will have an article with links to the correct blog. The "Just Takes 2" blog also has some basic information about the quilt (e.g., fabric requirements, etc).
