I called Stitch Connection. There are two versions. Number 1 is for shops, makes a bigger quilt than #2, and is the one I like. She sells number 2 to quilters, but only sells #1 to shops. She sells to shops because it is a good way to encourage business for quilt shops and she still has shops that are interested, so she will continue to sell just to shops until that changes. I appreciate why she does that. She suggested I contact a local quilt shop that sells machines and see if they are interested in doing the #1 BOM, so I may do that.
