I used to make a lot of these about 20 years ago. They take a lot of hand sewing but I like to sit with my feet up on the couch and sew - very relaxing. It's not finished yet but you can get the drift.
They are nice and puffy, being stuffed on all sides and top with fiberfill.
The sides are sewn by machine, turned and then stuffed first inserting cardboard then fiberfill.
After stuffing you sew each edge closed (see the side under the button)
Then you slip stitch each edge closed.
I may try another and figure out a way to make a tab thing for a closure.
I finally finished quilting my beach scene and have started on another. Am making a pattern for it so will do at least 3 with some variations. Wish I was on the dunes right now.
Christmas next week already - have a Happy Christmas!
