I started out machine quilting using a John Flynn frame. I used it for several years. It took practice but once I had the Ah Ha moment it was as simple as John Flynn makes look when he does it. From all who I know that say they didn't like it they used it a few times, got frustrated then put it in the closet. I kept on trying. I give demos at guild how to use it. I had to go to one member's house. She bought one and could not move it right. I sit down and went to town on it. She sit down and made a mess. Finally she realized she was jerking the frame and not getting a smooth glide. Now she shows amazing machine quilting she has done for children's donation quilts at show and tell that she had done with the frame. For small size quilts it is really nice. Larger then a throw size gets to be a hassle for me.
