Look at these great pyramid shaped presents I made. You can actually make doorstops in any shape or cuddly toy pattern you want. Just add weight in the bottom part of the shape and voila, a doorstop is born.
It’s a great little sewing project you can make in an afternoon. I have quilted mine with one layer of flannel. This gives some sturdiness to the fabric. And of course you can use these small projects to practice your (free motion) quilting technique, although I decided to sew straight lines and simple designs which I could sew with my walking foot. As weight I used birdcage sand, as this is easy to buy and it is clean. I put the amount I wanted in double plastic (bin) bags and, along with some cushion filling at the top, inserted them in the bottom of the pyramid. You could also use rubberised fabric at the bottom to prevent the doorstop from sliding.
