Oddly enough, I just saw a site yesterday! These are holiday designs, but they probably have others as well.

I gave my family embroidered toilet paper for Christmas. They all thought it was a hoot. You can find about 100 designs at goodiesbygail. She has some really great sayings with designs. I designed my own for the ones I did, combining designs I had with the words. It was not very hard at all I even did a sewing machine that had about 17,000 stitches in it for my mom who is an avid sewer. I did not think toilet paper would take a design that dense but I was pleasantly surprised. I did figure out that I needed to slow my machine down and skip the first and last stitches of the designs. Let me know if you have any questions.

I have some on my site,including instructions on how to embroider on T.P.

I used the same low density designs I used for Christmas cards.
