As long as you've already appliqued that area go ahead and remove needed stablizier. It won't make a difference. Even if you bought new you'd be piecing it in so use the old and safe money. Even when I use water sol. stablizier on embroidery I save what I can before I desolve it and when I need two layers, I hoop it with one large piece and the spray baste the waters soluable and put it where the designs will go. it saves alot of money that I can spend elsewhere.
