for the oooh and awww. Thanks.
I only followed other leather workers process in their videos... I creased first, beveled the edge and burnished well with water and then applied the dye. Finished the edge with gum trag.
Oh if interested, I used a wooden creaser for the line. I have other creasers but this wooden one does a nice impression too.
Yes I skived the end from the buckle to about 1mm thick.
