This is the seventh pair of leggings you've had to throw away because everyone can see your butt.
You'll need a few things besides your best pair of crappy leggings:
Your second best pair of crappy leggings
Cushion stuffing, $7.15
1. Sew the ankles on your crappy leggings shut.
2. Stuff your crappy leggings full of cushion stuffing ($7.15).
3. Roll the top like a bag of chips and pin it shut so that you can sew it closed.
4. After you've done this to two pairs of leggings, knot them together.
5. Spin and tuck the legs around the knot.
