The most common repair I have to do, is fixing the crotch/inner thigh of my pants. I have performed this operation on dozens of pants, and it is very easily fixed, if you have a little bit of patience.
Step 1: Materials and Tools
- Pair Busted Pants (the inner thigh ripped out on this pair.)
- Scrap material from an old pair of jeggings I cut up into a skirt.
- Sewing Machine (you can hand stitch, but just try and keep really tight tension)
- Dark Thread
Step 2: Cut and Pin
Using a stretchy thin material will be easier to sew through, versus sewing two layers of denim.
If you are going to machine sew a patch on, go ahead and pull of whatever guards or feed trays off your machine that may be around your needle - you are going to want to have access to various grip points on the denim when feeding something like pants in the machine.
Step 3: Sew It!
Start by stitching down, then holding the reversing button/lever (that differs on every sewing machine I have ever used), gently pull the pants to the right.
Repeat this sequence up and down the patch until you get to the left border of your patch.
I then sunk my needle down in to the material and rotated it, sewing a final perimeter box around the patch.
Make sure you don't have any pins in it and then wear 'em!
