I'd love to try my hand at some Baltimore-type applique. Can you offer some suggestions of where I could find a good resource book?

Check this site, BOM are free each month or you can buy all at once. Nice patterns here.

I have always wanted to do a Baltimore Album quilt but I'm just not ready skill wise. Someday.

I love books by Elly Sienkiewicz...lots of gorgeous patterns and the history of them too.
