Groovy Men's Boxers

I bought a new over-lock machine, and I have been dying to make some boxer briefs and other stretchy stuff with it. This machine is a little quieter than my Brother over-lock machine, and I think it does give a tighter stitch.

This pair I made from an old tie-dyed T-shirt that I rarely wore. It's not super stretchy, but it is stretchy enough to be comfortable. 

This is my first pair, and next time I would use a little less elastic and make the gusset a little tighter, smaller. I also want to make a pair where the elastic is on the outside as in standard men's boxers.
