To those of you who have the DVD (CD?) of making a quilt block and/or quilt - how do you like it? I've been thinking about getting one for Christmas, but am worried I would spend too much time doodling on it or wouldn't understand how it works. Is there one out there that is better by far than the others? And do you spend too much time with it instead of actually sewing like I do visiting The Quilting Board instead of sewing?
