Our Ideas & Additional Information
Since I use a lot of reclaimed barn lumber, I have a love of old tools and old methods. I'd suggest looking at pictures of old woodworking or timber-framing tools for inspiration. Hand-hewn beams, old barn frames, things like that.
I'm looking for something that would translate well to a brand (as in a branding iron that I could use to mark wood craft items I make), and t-shirts, so probably restrained in the number of colors, or at least such that the logo would look good in black and white also.
