If you have some pajama bottoms where the elastic has
stretched out, you can always repair them. Repairing your pajama
bottoms saves money and is good for the environment as it helps
Here you will find the basic waistband repair as well as my own innovation in repairing stretched-out waistbands.
Things You Will NeedSewing machine
Needle and thread
Drawstring, cord, ribbon or extra long shoelace
However, If the elastic is sewn in with several rows of stitches like the image above, or if your pants have become stretched out and droopy, move on to step 2.
Step 2Leave the troublesome elastic in and create a drawstring waist. First, choose your drawstring. It should be more than a foot longer than your waist measurement to give you plenty of room to go around your waist and have room left to tie it. There are several things you can use for a drawstring: cord, an extra-long shoelace, or ribbon.
Step 3With your pajamas on you, turn the waistband over and see if that makes them too short-waisted for you. Usually, if your pants have lost the elastic in the waist, they are also stretched out in the length. Turning down the waistband might improve the fit in the length. When you are ready to start sewing, flip the waistband down from the outside to the inside so the outside of the waistband is smooth and the inside has the new hem. If there is a tag in the waistband, you may want to cut it out.
Step 5Feed the drawstring around the top of the waistband and hem the bottom of the waistband under the drawstring being careful not to catch the drawstring in any of your stitches. Be sure to push the drawstrings through holes before the hem is completely sewn. When you are through, your pajamas will have a new tight-fitting waistband as well as some of the droop removed. If you left the old elastic in (as I did), it will make the waistband just a little bulkier, but the pants will still look and fit much better than a stretched out waistband!
Tips & WarningsThe drawstring technique works best on knits and other soft fabrics and works well for repairing sweatpants as well as pajama bottoms.
