Now, for the next few pictures I will show you how I turn pants into a skirt at the request of a friend. I use wide leg pants or relaxed fit, boot legs work great. Straight leg is fine too. No slim fit, unless you like to feel like a sausage.
Turn pants inside out and fold together on the sides. Cut off the crouch in a straight line.
On the front I put my ruler right under the zipper and again, try to get as straight as possible. You want to remove all curves from the front and back.
All cut up, ready to sew.
I sewed the front together first. Try to get as close to the zipper as you can. Finish off seams with a serger or zigzag stitch. Iron seam to set it. Now, the back.
I am not very good with mirror design. I did sketch my design on paper first and copied off that. I should have drawn it own the jeans, but I got a bit cocky I guess. Oh well.
Now, go raid your closet. Or your husband's. (As long as you can button the jeans and sit down comfortably, you can make a skirt out of them that fit.)
