I have a new pattern in my Etsy shop.
The ottoman is 14″ high with a 19″ diameter.
It is fully lined and has a zipper at the bottom so it can be washed if needed.
I filled mine with polystyrene beads or beanbag filling, which gives the ottoman a great shape and makes it very light weight. They are not very child safe though, so consider using toy fill/stuffing or cutting off the zipper pull with pliers/side cutters and using a paper clip or similar to open the zipper when needed if you have small children around.
Happy sewing and take care!
