I thought everything was well planned, thoroughly explained & nice examples shown of the various techniques/ideas. Your class was a joy to attend & I like having recording to watch over & over when needed.

That Rachael is a very kind person who loves to share her knowledge on relining vintage train cases. Her course was virtual and fun to take. She helps you every step of the way if you need it. Very quick to respond if you have a question after and during class.
