"saskia_madding" a fellow member, Canadian Ink Goddess, you will find her "home page" which has a link to her KWS Blog. KWS is the abbreviation of her "KIND WORDS STATIONERY" writing paper which she sells on Etsy.
She uses Tomoe River (& other) paper & offers many designs. She might be willing to "customise" for your choice of design, but I could not say.
I have purchased & used her paper, besides given it as gifts; it is lovely. It made me happy to think I was helping support a fellow member who has been instrumental to the INK forums here. I am in awe of her expertise & knowledge of the contemporary world of ink. Her paper & designs of same is pretty darn cool as well!
