I have a full bolt of brown, beige, tan, grey, plaid flannel which is the perfect color combination for my new bathroom. I would like to make a bathmat/rug and matching window curtain. I want the bathmat/rug to be THICK. I am thinking about using many, many layers of batting and then tying the rug. My other idea would be to put an old bathmat inside for batting and then tying it. Can someone give me other or better ideas? Also, I know I can paint the bottom side with non-slip grip paint made for rug backing that is washable so that the bathmat/rug won't slid. Are there other products?
