Thanks Joe-rcsaddles, I asked them by e-mail.
Brian Stelzel of The Leather Crafters & Saddlers Journal emailed me and they have patterns for the two mule pictures but not the una copa mas picture. The patterns for the mules are located in the May/June 2007 issue. This issue is in stock and available for purchase at a cost of $7.50 (includes shipping in the USA).
leatherworker.net forum is the best, wonderful!!!! In a few hours I got the patterns. Thanks for your help, folks.
Playing with greyscales and filters in Photoshop I drew these sketchs. I'm not sure if these photos are a good pattern. What do you think?
