Carlos you head-case...! (mind you, I do have some spare black binding material I decided not to use on the Cookie...
)
I was planning to use veneer to fill but hadn't thought of using binding - that's an option...
Main issue is where the surface is damaged - look at the pic near the 20th- 24th also at the 8th... I had a local suggest using resin based heavy duty wood filler - similar to the stuff used on cars...?
