Got some leather a very kind moderator over on the British blades site is sending me some just ordered a over stitch wheel 4mm 7 holes to 1 inch. need to find a Edge beveller and Adjustable stitch groover.
Noooooo Cancel the 7 per inch if you can. Get a 5 per inch. Too close together at 7 per inch, and thats a LOT of sewing.
