|I have always looked at FBAs on pattern pieces and thought they were like another language I couldn't understand. It was a challenge I searched sewing books to explain to me in layman's language what was going on! I couldn't understand why the pattern pieces were all spread apart. Thanks to this class I now understand! I not only understand the slashed and spread pattern pieces, I know why they were moved and I know how to alter them on several different types of seams--raglan, princess, patterns with darts, patterns without darts! Sarah Veblen is an excellent instructor. In 7 easy lessons she'll teach you FBA and SBA. She's thorough, so informative, and quick to respond to any question. She has made FBAs so easy for me to understand. I can now speak FBA.
