By the way, I did put a little silicone sealer across that rear bow where I cut the top and gathered it. I just couldn't leave it without.
I ran a piece of masking tape as a straight edge (saw a bunch of convertibles at the Goodguys with the wire-on all crooked!).
And wham, just like that the rear was done!
It was at that point I found myself literally "giddy" with excitement.
Again, thank you so much!
