OK, done. 21.5 hours. All in all, I'm very happy. Two points to complain about: I need better straps and buckles. Don't like them. Second, the hole where the under apron strap comes through is not as nice as I would like. The hole will have to remain the same, while I will change the straps, at least, in short time.

Think I'll buy Barb's book as well, for neat tricks that I couldn't figure out myself.
