I say always make a new one.
Let your old work stand for it was the best it could be when created.
Its your history its PD history.
Now that we can communicate easier here, I'll tell you a story.
When I first visited PD 2 blocks stood out for me above all others,
one was an Amish barn that remains my favorite PD block, yup #1, the other
was the cave pople you made. If you go to my first the description clearly states that my grocery store does not serve cave people. Yes, you were instrumental in my joining here. Altering your blocks, alters our blocks.
