First of all, no its not cheaper. Yes, it can be done. I save my water soluble scraps and if I have a design that needs extra stablizer in one area more than another, I'll spray it with temp glue spray and put it over that area or use it to patch if I get a hole in an area while emb. If you are doing FSL, you can disolve some of the scraps to put the pieces in to make them stiffer. I also use it for topping on towels or if I'm doing an delegate design or text it helps it stay on top. I can buy a can of spray starch for less than a dollar and it would cost me more than that in stabilizer
