After working two days on this purse (not yet finished) I noticed the color of the silk faded on the flap but not on the main body of the item itself. Non color fasted silk will bleed during the felting process. Lesson hard learned. Let’s see what happens next. I have extra silk and have laid it on top of the faded section and drowned it in hot water, hoping it will bleed into the felted bag. Look for more pictures!
