Hi, I'm new to Leatherworker, so I'm not sure where to ask this but here goes. I've been reading the posts on here and picking up some really good advice but this is my first post. I make a few holsters as a hobby for myself, friends and family. This is kind of how my process goes. Cut out the pattern, rough in the edges, groove the front for stitching, glue the holster, mark then drill the stitching holes along the grooved stitching line, groove the back where the drilled holes came through, saddle stitch, wet mold, dye and finish. My proplem is the drilled holes. They work OK for sewing, but when grooving the back there are little raised areas that kind of look like mini gopher mounds around the drilled hole and it's really difficult to groove over these mounds and get a neat job. I've tried chucking up a needle and drilling the holes, but with pretty much the same results, except a smaller tighter hole to try and sew up. Broke a few needles on that one. This may be a crazy question, but it's been buging me for a while. This might be an easy fix, and I hope those of you with much more experience than I can help.
