Ok, so I'm experimenting with my own creation, knit from the bottom, gusseted crotch, shaped bottom, oh la la. I finish it up with more yarn left over than I anticipated and got the great idea to make the legs longer. But, since it is knit from the bottom up, I can't just pull out the hem and make it longer. So I get the bright idea to just cut off the hem, pick up the stitches and knit a few more inches. I took pictures. Those of you faint of heart, don't watch!
