Thanks for the info! Of all the attachments on the Dremel those little cutoff wheels require googles the most.
I can't count how many times they end up breaking and flying into pieces lol.
For the truck seat backs, they are pretty thick but I'll punch holes and see how much sticks out with a target of 1/16" - 1/8" and address accordingly.
I suppose it doesn't take much post metal to keep the snaps in place.
One other question, I went with Tandy snaps mostly because I was looking for a gun metal color - are these quality snaps? Is there a better option?
The ones I got on Amazon have the Tandy packaging but the individual metal pieces are not stamped with the Tandy brand which I saw in one of the pics - hoping they are not counterfeits.
