What is solvie? Solvie is awesome. Its a plastic bag type of stuff that was originally used for soiled linens so only one set of hands would have to touch it, because it dissolves when it touches water (so you'd throw the whole bag in the washer and then not have to deal with it after)
Once creative people got a hold of it, they realized that you can sew stuff onto it, and when you dissolve it you have (drumroll) LACE!
This is silk organza and thread. That's it!!!!
My whole class has realized solvie is made out of glue. So, if you want stiffness, you rinse it a little. If you want smoothness, you rinse it a lot!
