Making holsters is what started my business.  It is a time-consuming process. Following are the steps I take to create a holster.  All my holsters are made only from veg tanned leather.  

Step 1: The raw leather gets a good coating of oil, which then is allowed to soak in for about 45 minutes to an hour.

Step 2: In this step the leather is dyed. It receives two coats of dye, with a 45 minute drying period between the two coats.  After the second coat, I let it dry over-night.

Step 3: After the dye has dried, it is time to cut out the pattern. All the stitching is done and the edges are smoothed and burnished.

Step 4: It is now time to mold the holster. The holster is softened up by soaking it in  water. Once I am satisfied that it is soft enough, the gun is inserted and the molding begins.

Step 5:  When I am happy with the mold, the holster is set aside to dry. This can easily take up to 24 hours. 

Step 6: The last step is to seal the leather to make it water resistant. Now I can send it off to the client.

These six step take the best part of two to three days, depending on the weather and how fast the leather dries out.
