Copying a pair of favorite jammie or sweatpants-dl

I started with Tim's favorite threadbare sweatpants.

Step 1:
Carefully flatten the pants so the seams match and lay flat. Line up one side of the flattened pants on the fold of the fabric, lining up the side seam it they have one...

I double folded the fabric here, (so my pants are laying on two folds), that way I only had to cut once for both legs, instead of having to use my first cut out as the pattern for the other leg...

Step 2:
Add seam, hem and waist allowances with some kind of marking instrument. I used the same as the original garment, 1" for the hem, 1 1/2" for the waist and 3/8" for the leg seams.

Step 3:
Cut! I cut through four layers here, to get two legs cut on the fold. My scisssors protested a bit, but it worked and saved me the extra step of having to cut a 2nd leg.

Step 4:
Serge or sew the crotch curves, right sides together of course.

Step 5:
Line up the inside leg seams.

Sew them as one continuous seam, starting at one leg hem and finishing at the other.

Step 6:
Dig through your elastic stash and decide how you want to apply the elastic :) based on what you find there...

I decided to go with a drawstring elastic waist like the original pants and a cased narrow elastic for the hem, because I didn't have a suitable width of woven elastic to do the hems like the original.

Step 7: (for cased hems)
Turn up the hems 1" to the wrong side. Stitch close to the edge, leaving a 1" opening to insert elastic.

Insert elastic using a bodkin or large safety pin.

Stitch elastic together into a circle, pull into casing and stitch opening closed.

Step 8: Drawstring elastic waist
Cut elastic about 25% less than waist measurement because this is stretchy stuff and it also stretches as you sew through it. His waist is 32", so I cut the elastic to 27".
(More pictures coming the next time I make pants)
Zigzag the elastic into a circle, being careful not to catch the drawstring in the stitching (ask how I know this...)

Quarter mark the elastic and the waistband (I used pins, a marker would likely work better).

Pin elastic to WRONG side of pants, matching your marks. I add pins between the quarter marks to make it easier to control the stretch while sewing.

Zigzag or serge the edge of the elastic to the pants, stretching as you sew.

Fold the elastic down and mark where the drawstrings are going to go thru.

If you are using a woven, you would make button holes. My origianl pants were knit and they were just holes cut, so that is how I did mine. Maybe you can cut your holes neater...

Turn the elastic to the inside, pull the drawstrings through the holes and knot the ends.

Pin in place and stitch, stretching between the pins.
