The skirts below are the ones I made for my 4 granddaughters.I just measured their hips and length since I used elastic waist.I just sewed up the sides,turned down the top for the elastic to go through and then sewed and pulled the elastic through,sewed it up,matched right sides together for the lace and sewed along and wal-lah,skirts,and they made it through the 12 month one who is walking,crawling and climbing.
