Thanks everyone for being so kind in your comments. I'm so happy right now that someone like it.
The quilt pattern is called Amazing. In answer to the long-arm question, I did it on a mid-arm machine (Bailey) at a sit-down table that came with it. It has a 15-inch throat. This machine could go on a frame, but I don't have room for a frame at the moment. So sit-down it is. Not sad about it though, because I had such fun.
And, yes, it is wonderful to learn something new.
