I want to make a cover for a book--found a pattern in Quilt Almanac 2012 that I am using.
First thing you do is cut the fabric for the main piece (11" X 18"), layer the backing, batting, and top. Then it says "quilt as desired". Here is where I'm stuck. I have never done hand quilting, or machine quilting--only piecing. Do I use my machine and if so, what kind of 'design'? The fabric is a batik with an overlay of flowers/leaves printed on it, so I don't think something too 'angular' would work....but I am at a loss as to what to do. Hand or machine? It's small enough to do by hand, but machine would (ideally) be quicker....I say ideally because things can always go wrong....

I have it all basted together, but wanted to get some guidance.
