I’ve been trying for years to get a pants sloper. I tend to try one thing after another and never stick with one method long enough. Anyway, now that I am “between jobs” I finally decided to use the most recent sloper I had and work with it till it fit. I finally got a great fit using that pattern fabric-paper stuff with the red dots on it.
So I thought I was ready to make pants. I tried a linen-cotton blend. I guess it’s because the fabric stretches and/or drapes and the pattern stuff doesn’t, but after much teeth-gnashing I finally realized I had to take in the entire rear crotch seam an inch. That is, basically draw a parallel line an inch from the existing seamline, tapering to a slightly different curve at the bottom to meet the original inseam point.
I bought several similar fabrics so I hope the other pants I make fit the first time around. But I really don’t want to have to make a muslin and fiddle with the crotch curve (which took me all those years to perfect!) on every different fabric. But I’m not sure how to avoid it. Does anyone have any suggestions?
