I'd say no tassels, those "dings" will be invisible to the average viewer. It's always hard to back off from your own creations and realize that what you see as flaws will be either invisible or ignored by people who are a few feet away vs. the inches away of the creator!

That's a great repurposing of the old sofa, BTW. I have a nice black leather jacket with unfortunate L-shaped tear in the front, have been hanging onto it for much the same reason. . . can't blame the cats, just my own clumsiness!
