Hey M.C.A!
I've got a spare 300 pesos. Will you give me $150 American?

Seriously though. Our guy in the market has repaired a couple of pairs of boots and a pair of loafers for me. Excellent work. He uses a hand, sail-making type of needle and a small hammer and last. As you said, similar to "DM's" stitching.
Anything leather, nylon, or canvas. Bags, backpacks, shoes, boots you name it he's a whiz! PhP 50 to 250 is the usual charge, obviously dependant on the item.
