I know, I promised pockets next. I didn't realise there was so much more to do before getting to the pockets, so here's one more post before I get to them.
I took some photos outside instead of inside at my dark work table. Wow. The photos came out so much better. It's just so hot outside right now, so I may not take all my photos outside. Also, it's hard to stop work to take a photo and then come back inside to keep working.
Here is the button catch, with the buttonholes marked and basted, ready to cut.
The finished buttonholes (with bright colours!). This button catch is lined with linen, and has a layer of wool on each side to finish it. Some of the buttonholes are better than others.... I've also made the finished side of the buttonholes face to the outside, even though they'll usually (and hopefully always) be covered by the facing flap of the button catch, but just in case they show they'll look neat and tidy from the front.
Here's the finished and lined button fly. Note the difference between "button catch" and "button fly". I had trouble keeping the two apart, which led to a lot of reading and re-reading to make sure I was doing what was needed to the right side. I also referred to David Page Coffin's Trousers book to wrap my brain around button flies (flys?). Anyway, this is stayed with a triple layer of folded canvas to provide support for the buttons.
Here's a shot of some of the additional stay supports in the trousers. Across the top are the waist stays, which are actually several shorter lengths of canvas, overlapped at the side seams and at the split points at the back of the waistband. Down the side seam is another stay, which goes to just below the pocket opening, and keeps the pocket opening flat, and also gives the pocket bag itself something sturdy to fell onto (in the next post). Finally you can see the two round button stays for the suspenders/braces. In the rear there are triangular button stays which go up into the back split points.
The top of the trousers are cross stitched onto the waist stays. This seam will be covered eventually by the interior lining. Not shown, I pick stitched all around the waist stay to the front, about an inch from the top, to give the waist the support it derives from the stays.
