Do you really need to insert a piece of paper into each wrapper piece before folding? No. The first purse I made I did this way but after making 4 or 5 purse I stopped. The only thing that inserting the paper into each wrapper piece is making the wrapper thicker to make the purse stiffer. If your making your very first purse I would say "LEAVE THE PAPER OUT". It's not a must and alot faster to make without it.
