Anabolina: that looks great!
Over the weekend I used a journal that I had purchased for less than $6 from Office Depot to create a cover for my 350. I want to make more now to match my eclectic reading tastes!
The artwork is by Patricia Ariel. I ripped out w/the help of an Xacto knife the journal pages. I have had the journals to play around with for awhile but was debating whether to put a cloth insert w/corner tabs or to try Velcro. Initially, I didn't want to do the Velcro.
I purchased a pack of Martha Stewart Essentials paper pad, that is marketed for scrapbooking to use for the new insert. The paper designs look much like the old fashioned boards of nicely bound hardcover books.
I used a spray adhesive glue called Tack 2000 to attach the paper. I definitely want to use a different glue next project. The odor of the Tack(y) spray stuff is overpowering and hard to be precise with. Had to spray it outside, my preference would be for a liquid non-toxic/acid free option for the next experiment.
I didn't get the insert as even as I would like. Next time around I'll be more careful and precise.
The journal cover folds over at the front, overlapping and includes a hidden magnet clasp I can also fold the cover inside out? to use as a slanted upright stand for the reader.

My New personalized Ereader cover for the 350. Front is an overlapping design with built in magnetic clasp.
