Things You'll Need:
- needle
- thread
- iron
- pins (optional)
-
Step 1
Trim your t-shirt if you are hemming it for a shorter length. Choose a length between half an inch and an inch longer than you want it to be when it is finished.
-
Step 2
Heat up your iron and turn your shirt inside out.
-
Step 3
Fold the edge that you want to hem up just a bit -- about a quarter to a half of an inch -- and iron this fold in place. Work your way around the entire edge, folding and ironing your fold flat.
-
Step 4
Repeat this process. Fold the same edge up again, about the same amount, and iron it again. This should give you a triple layer of fabric and no visible raw edge where your hem will be.
-
Step 5
Go around the edge one more time pinning your folds in place approximately every few inches, particularly if the folds seem unlikely to stay in place by themselves.
-
Step 6
Thread your needle with a long thread that matches your t-shirt, and knot the ends of the thread.
-
Step 7
Hold the hem edge in your non-dominant hand and make a stitch using your dominant hand. Sew down right next to the folded layers and up at the edge of the folded layers. This should be a very small stitch.
-
Step 8
Move forward and repeat this stitch about half an inch further along the hem. This leaves a relatively large stitch on the inside of the fabric (the side you are looking at now) but you won't see this when your t-shirt is finished.
-
Step 9
Continue the same way, making stitches about twice for every inch until you get all the way around your hem and back to where you started.
-
Step 10
Make several small stitches on top of one another to secure the end of your thread. Clip off the extra thread close to the fabric.
