Hi! Can you not just use your own colors? I made an "Aunt Bea's Parlor" quilt, which combines hand embroidered baskets of flowers (all different) and 1930's feedsack type fabrics. No color instructions were given. Right now I am working on an old set of state birds and flowers embroidered blocks from Aunt Martha's transfers. Only general color suggestions were given there, not specific thread color numbers. It's perfectly fine if you use your own taste in colors for your Baltimore Bride's quilt blocks. Give it a try!
This is my Aunt Bea's Parlor quilt.
