Done most of my leather work so far with standard intro tools - harness needles, standard punch awl, 1mm thread, etc. Looking to make an unlined watch band, using .5 mm thread. However, it seems that a typical punch awl will punch holes in the watch band that are too big. Am I missing something here? Are there different sizes of punch awls? Or how should I punch these stitch holes? Also, with these smaller holes, and narrower thread, is there a smaller needle I should be using as opposed to the standard harness needles Tandy recommends for starting? Thanks!
