Solvy Paper is a water soluble paper. Mostly it is used for PP. Solvy is a thin film stabilizer that is water soluble. AquaMesh is a water soluble stabilizer that has a woven texture. I've been playin' w a technique that uses a pre printed grid on a thin interfacing, only I gotta change things around. LOL I didn't like the fact that the interfacing would stay in place. It was Ok for a wall hangin' but if ya wanted it for something else...well not so good. So I've been playin w/water soluble things & drawin' my own grid. The Aqua Mesh seems ta be the best answer. I'm planin' ta do a tute on it in the next few weeks.
