|DanTwoLakes||It is made that way because that leather welt is heavy, and on an inside corner if the welt just had straight cuts, it could overlap itself and make a bulge. This way you can sew it to an inside corner or an outside corner and it won't overlap itself. That was sewn on a dedicated machine that sewed the welt and had a cutter to make those round notches. There are all kinds of dedicated machines in a sewing plant that only do one operation. The parts of your Cadillac seat from that long ago would probably have had the edges of the seat parts run through a serger which would have cut off some of the fabric and made an overlock stitch on the outside edges as it sewed the leather to the sew foam underneath.|

|Coodeville||That, I know - but why do they go through te extra step of making it so big ?|

|killeratrod||made that way to go around any curved areas and not kink up.|

Original Welt ?
Here's a photo of some original welt from a 1970 Cadillac. Why are the relief cuts made like this and not just regular cuts ?
