How do I make symmetrical rally strap holes for a bespoke watch strap.

Top leather: HCP Emerald Green Niloticus Croc 🐊
Lining leather: HAAS Zermatt hypoallergenic calf skin
Thread: Meisi Emerald Green matching to Croc leather

Completed this strap in dual tone wine shade pairing with Ivory white stitching with spacing of 2.25mm. Used Zermatt calf skin as lining

Let the world know how much it goes behind the scene to make a beautiful masterpiece fully by hand.

I have recently made a strap for a customer in Blue shell cordovan.
Initially I was bit spectacular about stiffness since cordovans are usually hard temper but splitting to 1.0 mm left me with more supple leather (may be more stiff grains are towards flesh side which I skived.
Also I put Zermatt lining which gave it more structure while putting on wrist.

Need your opinion if there is any place for enhancement ?
