The above pics are last year's pants from a patten I drafted myself. The crotch felt a little low, the legs were uneven (which wasn't noticeable when they were worn long, but when I rolled them up to capri length you could tell they slanted up on the inseam) and the tabs that held the rolled cuffs in place were to long and were constantly getting caught on the shift lever when I rode in the tractor, and I placed the pockets to low (they look to be around knee level).
Those were the issues I wanted to correct in this pair. To fix the crotch I took about a 1/2" off the front waist. I fixed the crooked inseam by slightly widening the leg and shifting the lower half of the leg toward the inseam by a 1/2". Instead of buttons, I went with D-ring for the tabs and raised them to slightly above the knee so when I roll the cuffs into capris, the cuff will fall just below the knee and the tabs are just long enough to be pulled though the D-rings about an inch, and because I raised the tabs, I also raised the cargo pockets and used the pockets to secure the side seam tabs. I'm happy with this pair, although I think they're kind of baggy in the butt (I think I've lost some weight in the hips and backside because I didn't change anything in those areas) and I think I'll go back to buttons for the tabs. The D-rings are a little hard to fumble around with.
Next I'm working on this pattern.
