Make your knickers !!

Cut or fold your undies so you can make your pattern. First Cut or fold on seam between front and back of the undies. Then fold each piece in half at the center.( I made a hybrid pattern from two different undies I liked different things about the cut of each)

Trace and cut your pattern pieces. There will be three pieces (front, back and the lining) that will be cut on the fold. You should cut the front panel first then cut the crotch off the front panel to get the pattern piece for the lining.

Lie the pieces as flat and symmetrical as possible on your pattern paper(I Try to use the manufactured straight edge of my paper as the center fold line, This way I know that line is straight) Trace around your fabric piece leaving about 1/8-1/4 " edge. At the hips add 5/8 to each piece(front and back ) for your seam allowance.

This pattern may take a bit of tweaking to get the way you like so use up and the oldest ugliest t-shirts on your first pair then you can make adjustments to your pattern from there

Cut and iron the T-shirt into usable fabric pieces. For my undies I just cut around the seams to free the front panel of this large mans shirt . I was using only the front image for this pair.

I cut the front panel from a large enough scrap of fabric I had in my cotton knit pile.

Decide and arrange any key design elements from your fabric.( I wanted stewie's face on the bum)

Pin, cut and Iron your pattern pieces from your fabric.

Zigzag your edges on the lining to stop the fray.

Attach your lining and your panties together. Make a sandwich aligning all the edges from their center; on bottom, front piece wrong side up, next back piece wrong side down, next lining right side down (longest width as the edge ) Zigzag stitch all pieces in place.

Flatten and pin the lining to the center of the panties to hold in place.Run your iron over everything to be tidy.

Sew both legs about a 1/4" from the edge with a zigzag crossing over the lining( treat the lining as the edge to sew from)

trim/ even up any excess edges

Attach trim to the legs.( I do not cut my trim in advance I work from a large piece and trim it at the end of the stitching)

Using a zigzag, topstitch the trim directly to the legs.

Attaching stretchy trim to stretchy fabric can be tricky, so if you have not tried this before practice on some comparable scraps to get the hang of it. I do not pin, I simply line up my trim overlapping the panty by about 1/4 " and slow and steady send it through the machine.

Most folks will say to try not to stretch either material very much however I do give a little tug to my trim, (not as much as I would with a woven fabric mind you). Maybe my machine pulls the fabric a little. This is something I worked out with my little Brother. That is why I recommend a little practice will take you far.

Attach one side of undies. With right side together with a zigzag (5/8 seam allowance).

Sew from bottom up matching up the leg trim. Finish the seams with a zigzag and trim

Trim waist line if needed to flow smoothly front and back

Attach trim to waist just as with the leg trim.

Finish by attaching other side of undies with right side together with a zigzag (5/8 seam allowance). Sew from bottom up matching up the leg trim and waist line. Finish the seams with a zigzag and trim.
