One of the reasons I keep vowing to weave more is the fantastic experience of sewing with handwoven wool fabric. It's plush, elastic, and quite easy to work with (though the fraying is a bitch). The simple cheater "plaid" I wove for my Kindle cover is a perfect example. I wanted a thick fabric that wouldn't require interfacing or lining but would still protect my precious Paperwhite from abuse, so I wove up some bulky weight handspun Falkland from Fat Cat Knits in the Chevalier colourway.
After cutting it off the loom (I have a 20 inch Ashford Knitter's Loom) I roughly washed it by hand and put it in the dryer on hot to full it. So cushy!
I didn't use any sort of pattern - I cut fabric for a tube twice as long as the kindle and a bit wider. I sewed it into a cylinder and closed off one end. Then I turned it right side out, sewed off the other end, and tucked it inside itself (so the end seams were together at the bottom inside), making a rectangular pocket with double thickness and no visible seams aside from the one inside at the bottom. Then I topstitched around the opening and down the side seams, to keep everything in place. One thing about sewing with handwoven wool is it is quite springy and stretchy - you have to be careful not to stretch it as it feeds under the presser foot, or it makes for ugly wobbly seams.
I added a flap closure, again in double thickness, by folding a rectangle of fabric in half, sewing the three raw sides (the fourth was selvedge so I left it open and hid it inside the case when I attached the flap), turning it right side out, and topstitching. I attached it along the top stitching line on the main case, and added a magnetic snap closure.
A giant coconut shell button easily covers the snap hardware that shows through on the outside, and looks cute as hell.
I wanted the flap to attach on the inside so it wouldn't pull open at the corners while crashing about in my bag, which would leave the Kindle vulnerable. I think it looks pretty sharp too!
I made a bit of an error eyeballing the original fabric amount so the case is a bit big, but that means there's room in there for my iPod too!
So. I should weave more. Seriously.
