I give mine a good dusting ever so often.I have several pieces around the house I made for my Wife.Can't imagine giving it up.But I do know where ya coming from.
I sold several last year a few this year,no Penquins yet,I have learned to stop trying to figure out why the Public buys what they buy.I just try to supply.
Love that pic.This is just me,If I,m going to have a Flag as a background I paint mine.But seeing that your going to be doing several of them,that may not be the way to.I agree find some foam sheets. And Thank you.
