Keeping the doona in the cover!

Here is my latest idea. My doonas are always getting scrunched up in the covers.
My solution is to use my snap press. I put snaps into each corner of the doona. Then the sockets of the snaps into the inside corners of the doona covers, I put them in the seam allowance so the snaps would be hidden.
Now snap the doona to the cover and turn the right way! Simple. Now off to test if it works. I may end up adding a couple more snaps in the side seams if the doona is still bunching.
