My sister in law wanted some comfy lounge pants. I liked the idea of the challenge of making pants for an adult. So I gave it a shot.
She gave me some of her favorite shorts to use as a pattern. Now these shorts were pretty tight, but that's how she wanted the pants--tight around the hips and then fuller and lounge-y.
So I took the shorts and lined them up with the crotch in the front and traced the front.
Then I did the same for the back. When I traced them onto my fabric, I used the line of the crotch on one side and measured it wide enough to fit around her hips and waist on the other side.
That gave me four pieces--two front and two back. I sewed the front to the back pieces along the long straight side. Then I sewed the two front pieces together at the crotch and the two back pieces at the crotch.
Last of all, I put the bottom edges of one pant leg together in a tube and sewed it together. When I got to the crotch I continued on sewing the next pant leg into a tube.
It ended up with the front being smaller than the back. (Which is how we are anatomically.)
Last of all, I sewed a fold over waist band on, and hemmed the bottoms. I'm not sure I like how it hangs in the front. I might need to think that one over some more. My first impulse is to say that it's too long in the front and too short in the back, but kids these days love low riders, so I don't know how it should hang.
But the back fits her nicely. And she loves how comfy they are.
