First of all, Hi to all and thanks for allowing me in. I am extreamly new to leather working, made a couple knife sheaths and a I pad cover. On this project, Im trying to make a molded cell phone case. using7/8 oz veg tan, I cut my templet out, then cut a frame to match. I streached the leather around the templet, set the fram in place, clamped everything down, and walked away for 24 hours. When I came back to it, the leather was spotted with mildue. My question is, can I fix it, or do I have to just trash it and start over, and what did I do wrong? Thanks for any help.
