Here is a template that can be used to create NE Princess baseplate pads from WE retro base pads.
Its created by using the original NE pad glued to a stiff cardboard back to give a good template to make similar pads from.
The picture is a bit fuzzy due to my camera
Do you have a scanner? If so, simply place the template on the glass, place a white sheet of paper on top of it, close the lid and scan a perfect image for posting.
I don't have a flatbed scanner, I haven't found one for a Win10 system yet...My scanner is part of my all in one printer at present. That doesn't mean I'm not looking for one though
