Freezer paper works great! I was really excited for an afternoon to myself - just me, a cup of cocoa, You've Got Mail, and my sewing machine. I found just enough gray flannel to make one pair, then since I didn't have enough "boy" fleece, I cut up an old snuggie. This was brilliant, I must say. I was able to utilize the sleeves so that I eliminated sewing a hem on the pants. Shazam! I was going to make the hubs a matching pair but ran out of steam. Here is a pic of the original pants I made the pattern from with the gray flannel pair. I thought I took a pic of both finished pairs but apparently not.
