Best Tailoring Trick I Ever Learned

Well ladies, I am about to show you a fix for one of 
the most annoying fitting problems ever. You ready?

Pants that feel like they're crotching you to death. 
You know what I'm talking about. 

You make a new pair of pants, excitedly try them on, 
and find that they pull in the front, or you can't sit in them. 
Grrr!!

It's the one thing that can really keep you from getting 
any fashion mileage out of your newly-sewn creation.
