Have whipped up this Tablet case for my mum today (it literally took all day!) Couldn't work out how to sew it up and it took forever unpicking and resewing. Still not necessarily the right way to make it up but it's done, just needs a bit of ribbon to keep the flap down. Will be looking to add this to my Etsy store soon for customisable/bespoke covers/cases.
It took 2 whole pieces of this green brocade and is very thick with two layers of wadding for protection also makes it a snug fit which is good.
