It looks like they’re veneered. The way I’d go about it would be giving them a sand/removing the remaining veneer and then either paint them or apply new veneer.
This is definitely the way I’d go about it too, but on the off chance OP tends more towards the crafts side of the spectrum, make it into a fun art project?
If you screw it up you’re right back to the beginning, remove, sand, start over.
Yeah I was thinking about getting a bit wacky with it, but I’m not sure if my husband would be on board. But I’ll start with removing the vaneer and sanding down, definitely. Thanks!
