You can make one yourself. Just take a cloth tape measure and measure around the roll of paper. Cut your fabric in a rectangle but add an extra 1/2 inch on all sides for a half inch seam allowance. Set the roll of paper down and trace around the circle part of it and add 1/2 inch to the circle for the seam allowance.

ERmitchell has given u the best info. I like to use felt for this. It's cheap & I don't use stabilizer when I embroidery on felt.*

Modo I think you hjave had a great advice from ermitchell Now you can make one that fits your choice.:0)

Here is an idea but I like ermitchell's better.

I am learning so much today. These covers are very cute, if you have to have toilet paper on display.
