For all the watch strap masters in the bunch:
I'm looking forward to trying my hand at a replacemnt watch strap for a family member and have decided on 1.2-1.4mm box calf outter with 1.2-1.4mm Zermatt calf liner. I would like to use lin cable thread but would like some guidance on which gauge would be most appropriate. Likewise, I am thinking of using a #9 pricking iron and would be interested in opinions on this as well for the project.
Thanks
When you say #9 pricking iron, are you referrring to a Blanchard #9? If so, I think that equates rougly to about a 3.0mm pricking iron. In my opinion, I think that would be a good place to start as far as spacing goes. Many people might recomment going with a 2.7mm pricking iron for a watch strap. Either way, I would recommend either the 632 or 832 Lin Cable. You might want to stitch a couple short lines of each to see which look you prefer.
I would probably need to see your idea for the strap, but I was thinking that I would probably recommend a bit thinner Zermatt liner leather.
