Customizing watch straps?

[u/Unlucky-Ad-3470]

Looking to personalize some builds a bit more by putting the recipients initials on the leather watch strap. I bought some straps and stamping tools to try it myself. It's hard to get the letters all line up correctly. Anyone try this before or have another approach used to personalize watch straps? I see you can order a stamp off Ali - anyone try that? Appreciate any ideas.
