thanks for your comment. yes i want to make old saddle stitch The point is that dixon irons tooth (1inch - 7teeth and 6teeth) is big, i assumed the width of one is between
2,5mm-3mm width, if its true then my stitching would look awfull as the actual width of one stitch is about 1mm. In this situation the actual awl size would not change anything because even with small awl blade pricking mark remain the same.
Or maybe those pricking marks will disappear? Its depends on leather also i think.
you can see problem i want to avoid here
also i attached some zoomed picture from bowstock tutorial which gives proper display of the big difference between actual stitch and pricking mark.
thanks,
Jon.
