I've started making my pouffe/ottoman using a pattern from a book for a beanbag. Hopefully once completed it'll be a little bit like a large Amy Butler Gum Drop Pillow as I shall use lots of stuffing rather than beans.
So far I cut out and sewed up the inner, including a zipper in one side seam to make stuffing easier.
I chose a light coloured print fabric in cream and beige (sheeting I'd used as curtains, then recut for something else etc) to make the inner so it wouldn't show through any outer layer. I'm planning on using home dec fabrics in shades of cream and gold for the outer layer but haven't chosen them yet.
