This is one of those projects that is so darn easy with such pleasing results.  Even if you are a new sewer, you can make these.  The directions are super easy and super detailed.  The biggest problem I had with these is showing them to you.  Because really, am I putting my photo on the internet in my jammies?  No, I'm not sleeping in these.  No way.  Ahem.
Lounge Pants from Amy Butler's In Stitches book. I used a thrifted sheet out of my sheet stash. (Idea prompted by Soulemama)  I think I paid $2.00 for it.  I am so tempted to use every sheet I have to make more.  Although, I will restrain from doing that, I will make more.  A few more.
I omitted the trim from the bottom, because, well I just didn't feel like doing it. This pair is a little long.  Just a tad.  However, with the fit and the comfort level, these have fast become my favorite lounge pant.
