I tried the lighter weight Pellon (iron on) found it didn't give it as much body as I wanted. I normally use the heavy weight, that I get a Wal-Mart that is $3.97 a yard. I started out last one with the light weight, and ended up ironing on another piece of the heavier Pellon because it didn't have the body I wanted. So what I did on that purse was used the light and heavy weight on the outside, and left the light weight on the inside, that is something that you have to try to see if you like it or not.
