Mid century slipper chair - leather

[65Buick]

True that Paul. In this case I found the leather to be stretchy and workable, some of the best I've come by. It is reputable brand.
For me it's about skill - b/c once the hole is made, there's no going back.
Also, would you have trimmed under the tackstrip so the nail has nothing to go thru but wood?

For leather and a corner like that I would trip as much as I possibly could everywhere I could as long as it didn't show. You can trim pretty close with leather and vinyl and it won't fray.
