It stands for Block of the Month, quilt block of the month.
I have found through the past two years, alot of blogs dealing with quilts, have designed their own block of the month. The blocks of a quilt are published once a month for about 12 months. I have downloaded a cute Noah and the Ark crib quilt that way, remember, you'll never find a BOM in the local shoppes.
The painted quilt, is featuring this adorable Raggedy Ann and Andy, redwork quilt.
This is BOM number 1. I'll post the others in a few weeks, thus far she has released only 3 blocks. I'm unable to transfer the pattern but it's linked from her blog.
