I don't see the point of making one if you won't let anyone use it.
They are sewn very securely and wash up beautifully. No raw edges anywhere.
The one I made is rectangular but I think it would be the same if you made the oval one.
QuiltE- I agree with everything you said.
Another thing I just thought of- they are a lot easier to make than I thought. Once you get in a rhythm they work up quickly.
