:angel_not: Vera,
You do some of the most beautifully unique work that I've seen lately. These folders are gorgeous. If the wrinkles you're concerned about are in the lining of these photos they add character to the piece. If they are in the center fold, it may be better to apply the lining after you fold the back and trim the edge. Just an idea that works for me. On a bend, you are usually going to have belly (fat) wrinkles. It is the nature of the cut of leather. You might try skirting or a thicker cut of shoulder. I'll check on some other ideas from the tannery and get back with you.
We would love to see you and/or your work in the International Federation of Leather Guilds competition and seminars at Fort Worth in October. Wow, you could teach a class and demonstrate your techniques for the attendees. Anyone not attending your class would loose out on a wonderful experience.
Drop me a note at and I'll send you some information on the show. Time is running out as it is from October 19th-21st and there is a deadline for receiving entries unless you are a walk-in on Friday the 19th.
Again-GOOD WORK!!
