~ I sewed view A/B: I did not use the interfacing the pattern called for, but I added an extra little piece of fabric to the button/button hole area, to reinforce it. Problem: the "automatic" button hole maker malfunctioned, and I ended up sewing the button on through ALL the layers, so can't un-button: over the head it goes! OH! And I cut a HUGE size, because according to the measurements, that is what I needed: guess what? Immense relief: I did not! I had take it in at the sides- looks a little funny, but it works!
~It is cool, and it was great for mowing- I could see me making a new one every few years!
