Folding a Fitted Sheet

After I fold my sheets, I put the flat and fitted sheet plus the pillowcases inside one of the matching pillow cases. I then stack those bundles in my linen closet. I used to have a problem when had all the stacks of different sheets they would sometime fall over. And the same happened with the pillowcases pulling the ones I wanted out of a stack. They would become a tangled mess. And I don't have that problem now. I just pull one bundle out and know it will have everything together.
