I was interested in redoing my seats in a leather weave like the Singers after getting up close and personal with one a couple weeks ago. Did a bit of searching and found a supplier.
From Spinneybeck
minimum order is 55 square feet, for 1-2 leather weaves it's $55/sq.ft. So, just a touch over $3,000 for a new order of this stuff.
It may be needless to say, but I am no longer interested in going this route...
