I was finally able to get my wife's kindle cover finished up since I'm on vacation.
Did the whole thing out of some 8-9 oz (scrap piece from Zack White) and then ended up putting a lightweight calf-skin liner in it to hold the elastic bands since the linen was only going to tear out. She opted not to have a closure system since it will pretty much always be in a bag of some sort.
Really need to work on keeping even tension on my lacing, but the important person likes it (or at least she's just happy I'm done with it).
