The first thing I did was try to take out the elastic. This would have been a nightmare because the fabric is really loose weave and thin. The thread is completely embedded into the fabric and almost impossible to get out. I decided to just cut it off completely.
Next, I got some elastic and cut it to fit a little below my waist. I sewed it in a circle and divided it into fourths. I pinned it onto the skirt lining up the Front, back, and side seams with the 4 marks on the elastic. I zigzagged this on while I stretched it. That's why the zigzags don't look very even.
Then, I folded the elastic to the inside and pinned it. I used a lot of pins so that the fabric wouldn't get off. Both the skirt and lining are cut on the bias, so it's easy for it to warp.
I stitched this down only about 3/8 inch down, leaving the rest of the elastic free. I learned this little tip from Loes Hinse. She said that it works well for those with a much smaller waist than hips, I usually use 1-1/2" elastic for this, but this one is only one inch.
This skirt is really comfortable, and I think I will be wearing it a lot!
