Finding invisible prick marks on textured leather.
Is there a trick to locate or highlight prick marks on heavy textured leather? I am making several (7) of the current leather zip wallets for Christmas gifts. I made the mistake of making one of the exterior cases out of black Togo leather. I pricked all the way through one month ago and I cannot distinguish a single mark. I have tried chalk, bright task lighting, bending the leather and looking at different angles-no luck. Presently I am looking at attaching the interior pieces and using an awl to prick all the way through from the inside and casting each stitch. I am concerned with
creating tears, etc with the opposite direction existing prick holes. I would like to salvage, but I have no problem tossing in my really full lessons learned trash box and starting over if I cannot make to my current expectations since joining Philip's classes.
I am making seven. All are at different stages. I have three interiors to do and finishing to the other four. All are different and most are textured or embossed outer cases. I will send pics of all after I complete. Christmas gifts for Sister, half-sisters, and stepsisters.
