I would agree that it depends on what you do for cover fabric on what to charge. This one took more time because I used a bunch of the different stitches that my machine would do. I am sure a single piece of fabric would go much faster. I was able to do the front from scraps, so in that case the cost was pretty minimal. I plan on trying one with elastic on it in the future, so you can keep the kindle in it while reading it. I will post pics as soon as it is done.
