My husband has also become excited about playing with my new long arm and he expressed an interest in experimenting with doing a custom quilting job. To be honest, I gave him what I thought was my ugliest scrap quilt to play with because I figured I wouldn't be upset if it didn't go well.
I definitely wouldn't have tried something this advanced without his encouragement/badgering. This video was particularly helpful. We spent all weekend on it and I'm really happy about how much we learned.
