I'm pretty happy with how my first time doing harlequin turned out. 100% re-used wrap. Dirty but kinda cool. Things I learned:
- Newbaums can be re-used if you keep it intact when unwrapping from an existing bar, even if it was shellecked. The sticky still works. Part of it even ripped but once I wrapped it it stayed in place.
- The colors fade pretty quickly so I wouldn't worry about anything you choose being too loud. Maybe shellac might keep the colors brighter longer?
- It was tedious but not particularly difficult. As others have said the hard part is keeping the criss cross straight oriented. I didn't worry about it because, well, just look at it. :)
- I was happy with how the faded/unfaded parts of the green & blue tape almost created an extra color combo.
