Not a recently finished object, but a finished object of a while back - I think I actually sewed this kitty bed up a year or two or maybe even three years ago! Luckily for me, my cat Troy has recently claimed it as his own, after ignoring it all this time! As a result, I've finally managed to get a good photo of it in use :)
The bed walls are just deep enough for him to curl up inside, and not be seen, if looking at it from the side. I simply made it up as I went along.
Materials: Festively decorated (oooh! Christmas lights!) Fabric - cotton print, I believe. Felt or fleece for the lining, and polyfil and batting for the filling.
Approximate method: In addition to sewing this, I sewed up a bunch of circular "tuffets" for the cats - the "tuffet" provides the base for this cat bed.
The circular "tuffet" simply consists of two circles of fabric, the exact same size, filled with a combination of batting and a bit of polyfil to add fluff and stitched in the center with an X to form a divet.
The walls of the cat bed are made of one long tube - it's long enough to just overlap itself when wrapped around the tuffet - I estimated the length required by measuring the circumference of the un-sewn tuffet circles. Once the tuffet part was complete, I sewed and stuffed the long tube for the walls. At that point, I had a round tuffet and one long stuffed tube - kind of like a cat sized body pillow. If you're inclined, pin the tube around the tuffet and sew in place - if you're like me, and dislike pins, grab the tube and the tuffet and whip stitch em together. The way I sewed mine together, it is kind of reversible, so that the felt part is on the outside - but I think the cat prefers it the way it is :)
