My guess is that a liner would make it thicker and stiffer. Making it harder to use. Also if it is a production item it could be a cost factor, both in material and labor.
That would be another reason......wet dye will smear. I also remember several suggestions to let it dry then buff till no dye comes off before proceding with the next step. That way the dye won't smear
I would also throw the suggestion out to practice more with swivel knife cuts. Looks like the knife was dull and dragging. A good stropping and practice will fix that.

I can gladly say that Bill is a relatively new "friend" of mine and I can't wait till we can get together and learn stuff from each other. Congrays on the nomination Bill. I know you will make a great ambassador!!

There are several glues you can use. Rubber cement is one and I have a tube of gorilla super glue I sometimes use. Contact cement would also work as you won't want it to move after you glue it and prior to sewing. I am sure others will chime in also.
I went and spent a day with Chan Geer a couple of months ago. It was nice and inspirational. Wish I would have had more time. I would like to mentor with other workers too when I can.
