Literally just looking at this and the "Toby" nostr:npub1v0tfjv5ahr3c260jtzdk5w48krerrnkg8fmcnc5lpguk0qda04eqzm3m3e suggestions?
This is one of nostr:nprofile1qqsx845ex2wm3cu9d8e93xm282nmpu33emyr5aufu20s5wt8sx7h6uspz9mhxue69uhkummnw3ezuamfdejj7tr2s0f 's wallets after one year of regular use.
Not a single stitch out of place. It's the best wallet I've ever owned, and I bought it with Bitcoin. Worth each and every one of 210,000 sats.

And today he's only asking for 100k sats and it's probably double the quality.

And it looks like the product pictures are of this very wallet when it was minted.

Color suggestion?
Yeah sorry. Could have been more specific
I'm leaning towards the Mirror I think, I'm colorblind so images are tough sometimes, should probably stick to blacks and browns, except the stitching.
I like the black outside with a lighter brown interior but I'm not sure which, was thinking walnut...
Although my painter brain is yelling at me to go for emerald or sapphire...
Oh! Emerald and Sapphire are GREAT. I love them paired with a brown leather. Here's what it looks like tabacco and Emerald on one of my wallets

I never mixed black and walnut so I can't show you one of my wallets but here's one I found on Google. The pairing of those two colors would look like this. Looks very cool.

Imo I would go with a brown thread that matches the walnut so that the thread contrast on the black where it matters. But that's your call. If you prefer that the thread blend in more then black thread would be preferable.
Oh I like that, I'd prefer the thread pops a little to contrast the black, I'll leave the thread artisan's choice... Maybe that's where some color could come in 🤔, but a nice matching brown works too.
