I just received my HH Explorer back from 2QZQ (mod 3 - rt side zipper). So glad that I sent it to Donna, rather than doing it myself. I've made and modified gear since the 70's on an occasional basis. It's frustrating for me as I want professional results, and they're hard to get if you don't put in the years learning all the fine points and developing/maintaining your sewing skills. Donna's work is extraordinary. She's figured out all the little details that make for a strong, durable and professional looking result . . . could that be because she is in fact a Pro? ;-)
All the other aspects of my dealing with Tim and Donna were exceptional as well. Can't recommend them enough.
