I did find some time to iron on Devovil on the other pieces of my bag but for more there was not time enough. Five to ten minutes did it take to iron on the Decobil light on one side panel. Then something else had to be done. But this was good for the stabilizer as to cool down enough.
The cutted Devovil was slightly curved but after ironing onto the fabric it is absolutly flat. It also does not feel so stiff as before. Now I am looking forward as how is behaves while sewing it.
