SewLibra:
Used my pants sloper to alter a commerical pattern. The sloper was made some time ago from altering the heck out of a Butterick pattern. Ripping apart RTW that fits you works too.
SewLibra:
The sloper is for knits with an elastic waist, so I needed to add ease for flannel, which is a woven.
SewLibra:
I didn't need much alteration for the front crotch curve. There is room on the tissue to add the inseam ease. I did not add ease to the crotch curve, just used a small seam and serged it.
SewLibra:
Marking a cutting line. I slightly tapered, but not as much as usual so the plaid would hang straight.
SewLibra:
Cutting off the excess. I had cut out a small from the commercial pattern, and look how big the legs would have been. After all the changes are made, I will make a sloper for wovens with elastic waist from the tissue.
SewLibra:
Lay the front piece tissue over the single layer of right side up fabric. I centered the main color. Cut one front. Turn over the cut front piece and match the other front to the plaid. Repeat for the back pieces.
SewLibra:
I only had 2 yds of fabric because I didn't know what I was going to make when I bought it. For such a large plaid like this, you need a lot extra! I was 1.5 in short so took it off the waist.
SewLibra:
Trimmed 1.5 from the waist of the other pieces so all front and back pieces were the same.
SewLibra:
From a soft knit, I cut a 2 in strip to compensate in the waist band. The knit will be on the inside, against the skin.
SewLibra:
After sewing, I serged the seams. You could serge only, but I had so many pins and wanted to go slowly with the walking foot.
SewLibra:
I pinned the knit strip to the waist raw edge, right sides together. Sew in place. Serge other edge of fabric that will be folded inward.
SewLibra:
After sewing on the knit, I pressed and edge stitched at the seam to keep it from rolling. Then turned under the knit and topstitched on the right side to make a casing. Leave a few inches open for feeding your elastic through.
SewLibra:
Overlap elastic about 2 inches and zig zag near each end of the overlap. I zig zig forward and back to make sure it stays. Fold in the edges of the hole and stitch closed.
