step-by-step of marking and cutting holdfast on insole
Part 1
- for a square waist
- draw holdfast in a little through waist, on both sides to avoid heel breast wider than rest of heel
- opens 2mm incisions with screwdriver
- skive waists down to avoid ugly step after lasting
- 45° for inner holdfast incision
- about 30° channel on inside
Part 2 (doing the heel)
- welting without welt
- pierces from the outside in rather than inside out
- hole about 4mm from feather edge
- first hole through skived end of welt
- to finish, put awl through first hole from welting, put only the outside thread through
