I happened to catch a scrapbooking show on the DIY channel and saw the coolest idea.
Apparently there is such a thing as “dissolvable” interfacing. What this woman did for her scrapbook was take a piece of this interfacing, spray it with some sort of sprayable glue, lay pieces of fiber all over it, spray it again and put on another piece of interfacing. Then she sewed the whole thing together in a grid and dissolved the interfacing. The pieces of fiber then remain sewn together but very flexible. I took one look at that and thought: Oooo accessory.
Now, I have not found this mysterious “dissolvable” interfacing yet but I’m looking. This is a very intriguing idea. Such possibilities!
