Face mask-was so proud of my merging designs, rotating slightly, mirror imaging and I hadn't worked on this stuff for a long time. I even managed to figure out how to delete colors I didn't think I needed--used a Cuties mask shape and a couple of designs from a birthday going online now. Well I accidentally deleted a color I needed to had to delete from the opposite side of mask also. Then I hit the backing stuff with hot steam iron that I used to hide the bobbin and yet keep mask light enough and breathable and commenced to melting a couple holes in the back. Not too smart--fall off a horse and get back on when I can.
How did you do you changing colours and merging? Most software has a undo button for when you don't like a change you made.
Even with all you say went wrong it looks perfect to me.
Best wishes and hugs, Lidia
