Wow I may have to try this. So you literally just soak some grounds and bury the case in there, let it sit overnight, and then wipe it down?
I see I've returned too late to really answer this as you've already done it
Any other way to get this look without coffee beans?
Yes. There are several techniques for aging and staining leather. I'm far from an expert on it but have done several items and iPhone/iPad cases over the last few years.
You can use stains like shoe polish, wine, coffee(just the coffee without the grounds), olive oil, leather oils(like for baseball gloves), etc.
You can also open up the leather and/or remove the sealers to get the stain to take a deeper hold. Lightly sanding, steam, acetone etc all help to get the stains in there and/or scuff up the look to help an aged effect.
Can be done on any color case really. Just depends on the final look you want.
That looks awesome! I'll post some more pics when I've been using it for a few days.
This wasn't my idea originally btw. I can't remember who it was but I give the credit to them haha!
Thanks. That was me. Im not really a frequent flyer here so feel free to just share the ideas. No real credit needed
