I made a pair of flannel P.J. pants for my toddler for x-mas. I did not have a pattern, or a tutorial to follow, but I remembered making a pair in my high school sewing class, so I just decided to dive in a try it (I got the fabric on sale for $1 for a yard) so I figured I didn't have much to lose. I used a pair of her everyday pants for a guide. I forgot to take pics, but I plan on making another pair for me, so I will post a tutorial then.
these were one of those "errors" I was talking about, because I spaced it when I was cutting the fabric, and the backside or the pants has the fabric upside down, I was too lazy to cut two new pieces (I didn't want to waste my cheap fabric)
