Well Marion you got me beat! I haven't even started to lean 'gimp'!
The cutting looks great and as far as the 'blemish'..."we look at the whole job by nature, pattern, cutting, wood, backing, etc."
Others look at "The Big Picture"! They tend to look at the faces where we tend to be 'self-critics'.
I can't see the blemish when I pull up the pic so I would sand, clean, and apply a clear finish with no stain, use a dark backer and an attractive frame.
