That's awesome that you like the idea. I am sure you will make it look and feel a lot better than my little sketch but i am glad the idea was conveyed well enough to get your wheels turning.
I heard that song on the movie John Wick and didn't like it at first. Then it stuck with me... and now i listen to it from time to time.
I'm super glad you have enough fabric left. I was concerned about that. hahaha It has a nice pattern but the texture looked cool too. I'm excited to see how the top comes out when/if you choose to work on it. Cheers my friend.
