Who doesn't love fleece pajama pants? These are going to be Christmas gifts for my children, although, I may have to make myself a pair too! I may try to make them matching shirts, and probably a pillow case too. I didn't use a pattern, I used a currently fitting pair of jogging pants as a template. This is what I did:
Hem both legs. Here the picture shows everything finished except the waistband. Fold down the top 1/4 in larger than your elastic. I used 3/4 in elastic. Sew around the hem, leaving 2 inches not sewn. Use a large safety pin to thread your elastic through the waist. Sew the elastic together, overlapping an inch, using a zig zag stitch. Close the hole with a straight stitch, and you are finished!
