re: Asanoha Kumiko

For backing of a Kumiko project, like lamps is usually a shoji paper.   Believe it is a rice paper.   It is glued on with shoji nori glue.    The glue comes in a small squeeze bottle that is made to put a line of glue down each piece of the project.    Was surprised to find how easy it was.   Worked great on some lamps.   After the glue dries the paper can be sprayed or misted and then will shrink slightly to be nice and smooth     If you made model airplanes as a kid same as on the paper covered wings and stuff.  
I got the nori glue and the paper from a company off the internet   Quick ship and the price was good.  I think the bottle of glue was under $5.   I have no connection of any kind with this company.
Shoji.com    Franklin Wis.    414-367-2501     also info@shoji.com   Found that on the how to sheet they send with the paper.   You can find the glue on Amazon also, different brand.
Hope this helps.
