Bringing Luxury into Bookbinding

I’ve been exploring ways to elevate my bookbinding projects with a touch of luxury, and I’d love to hear your thoughts. What materials or techniques have you found really enhance the feel and look of a book? I’m curious about incorporating elements like fine leathers, custom embossing, or even unique closures that make each piece stand out. How do you balance aesthetics with durability when aiming for a high-end finish? Any tips on sourcing quality materials or adding personal touches that resonate with clients would be amazing.
