How to Hem Shirts

Hemming a T-Shirt

Turn your shirt inside out. If you don't already know how short you want to cut your shirt, put it on, and make a mark on it where you want the new hem to be. You can use a dressmaker's chalk, dressmaker's pen, or even a sewing pin for this. Take the shirt off when you are done, and keep it turned inside out. This may also work on other shirts made from stretchy material. It is not recommended for shirts made out of woven material, such as linen, due to fraying.

Cut your shirt ½ inch (1.27 centimeters) longer than you want it to be. If you want to be extra neat, draw a line using a dressmaker's chalk or pen first, so you will know where to cut. Use a ruler to measure up from the bottom edge of the shirt as you draw the line. This will ensure that the shirt will be the same length all around.

Fold the hem up by ½ inch (1.27 centimeters). This will be the inside of your hem. Your shirt should now be the exact length you want it to be. You don't have to double-fold or finish the raw edge, because T-shirt material does not fray much, if at all. If you want a nicer finish on the inside, then you can serge the raw edge, but it is not necessary.

Press the hem flat with an iron. Make sure that you use a heat setting that is safe for the material your shirt is made out of. This will give your shirt a nice, crisp edge all along the bottom.

Secure the hem with sewing pins. If you do not own a sewing machine, or if you do not know how to sew, slip some iron-on hem tape into the hem first. The results will be stiffer, but at least you won't have to do any sewing.

Sew as close to the raw edge as you can using a zigzag stitch or a stretch stitch. Use a color that matches your shirt, and remove the pins as you sew. For a more professional finish, you can use a double-pointed needle. Alternatively, you can sew a second line right beneath the first one; this only works with the stretch-stitch, however. If you are using iron-on hem tape, simply iron over the hem following the instructions on the package. Be sure to sew back and forth over the start and end of your sewing a few times to prevent unraveling. Try to start sewing at one of the side seams. This will help conceal the start and end of your sewing better. Expert Answer Q When asked, "What are some skills to practice when you're first learning how to hem?"

Lois Wade EXPERT ADVICE Answer from Lois Wade: DIY crafting and sewing expert, Lois Wade, responded: "You want to take evenly sized stitches, spaced close enough together so that your hemmed edge has no sags, puckers or gaps. If hemming a curved edge, you'll find that you need to either gather the sewn edge more closely, or loosen it somewhat in order to allow the hemmed edge to lay flat when sewn."

Snip off any excess or loose threads. Your shirt is now ready to wear!

Hemming a T-Shirt Using the Original Hem

Figure out how short you want your shirt to be, and make a mark on the outside of the shirt. If you want to, you can put the shirt on to determine the new length. Keep in mind that your shirt will be about ½ to 1 inch (1.27 to 2.54 centimeters) longer, depending on how wide the original hem is.

Use a dressmaker's chalk or pen to draw a line all around the shirt at an even distance from the bottom edge. Spread the shirt out on a flat, even surface, right-side-out. Use a ruler to measure up from the bottom edge of the shirt every so often. This will ensure that your shirt is the same length all the way around. If you can't find a dressmaker's chalk or pen, you can make the line using sewing pins instead; just be careful not to pin both sides of the shirt together.

Fold the hem up until the bottom edge touches the line that you drew. Keep folding your way all around the shirt. It should now be a little shorter than before. You are still folding on the outside of the shirt. Do not fold the hem on the inside.

Sew around shirt, as close to the selvage edge as you can. Use the zigzag stitch or the stretch stitch on your sewing machine. Make sure that your thread color closely matches your shirt.

Fold hem back down, and tuck the excess fabric inside the shirt, away from the bottom of the hem. Keep your shirt right-side-out. You should now see the original hem, the hem's original stitching, and your new "seam" just above it.

Press the hem with an iron. Focus on the new seam you made. This will flatten it, and make the bottom of your shirt smoother. If you'd like, you an secure the hem with sewing pins, although this is not necessary.

Top stitch as close to your seam as possible. Anywhere between ⅛ to 3/16-inch (3.2 to 4.3 millimeters) away will be plenty.Use a stretch stitch for this step, and be sure to go back and forth over the start and end of your sewing a few times to prevent unraveling. Start sewing from one of the side seams. This will help hide the start and end of your sewing better. If you secured your hem with sewing pins, be sure to pull them out as you sew.

Turn the shirt inside-out and cut the excess material away. Try to cut as close to your stitching as you can. Discard the excess material, or save it for another project. When you are done, go back over your shirt and snip off any excess or loose threads.

Turn shirt right-side-out. Your shirt is now ready to wear.

Hemming a Button-Up Shirt

Figure out how long you want your shirt to be, and make a mark ½ inch (1.27 centimeters) below it. If you need to, put your shirt on first. You are making the shirt longer, because you will be folding the hem twice to conceal the raw edges and prevent fraying. This method may work with other non-button-up shirts made from woven material, such as tunics and peasant blouses.

Use a dressmaker's chalk or pen to draw a line all around bottom of shirt, using the mark as a guide. Spread your shirt out on a flat surface in front of you, with the inside facing you. Draw a line along the bottom edge of the shirt. Use a ruler to measure up from the bottom edge of the shirt to the line that you are drawing. This will ensure that the line is an even distance from the bottom edge of the shirt. Most button-up shirts have a curved hem, so your line should curve as well. If you want your shirt to have a flat bottom, simply draw a line straight across the bottom of the shirt. Align it with the shortest part of the shirt, usually at the side seams.

Draw another line ½ inch (1.27 centimeters) below it, and cut along that second line. When you are done, you should have a shorter shirt, with a line drawn all along the bottom edge.

Fold the bottom edge of the shirt upwards, using the first line that you drew as a guide. You are folding the hem up by ½ inch (1.27 centimeters), so the first line that you drew should now be inside the hem, right along the crease.

Press the hem flat with an iron. Make sure that you are using a heat setting that is suitable for the material you are working with.

Fold hem up by another ½ inch (1.27 centimeters) again, and press it flat with an iron. This will give you a clean, professional-looking hem. The raw edges should now be concealed inside the hem.

Secure the hem with sewing pins, then sew as close to top edge of hem as you can using a straight stitch. An easy way to do this is to align the edge of the sewing machine's foot with the bottom edge of the shirt. Remove pins as you sew, and be sure to use a thread color that matches the fabric of your shirt. Remember to sew back and forth over the start and end of your sewing. If your shirt is not a button-up shirt, start sewing at one of the side seams. This will conceal the beginning and ending of your sewing better.

Snip off any excess or loose bits of thread. Your shirt is now ready to wear!

Hemming a Button-Up Shirt Using Bias Tape

Get some single-fold bias tape that closely matches the color of your shirt. If you can't find a matching color, choose a neutral color that is a similar shade. For example, if you have a dark blue shirt, and you can't find any dark blue bias tape, get black bias tape. If you have a light blue shirt, and can't find any matching bias tape, get some light grey bias tape instead. This method works great on shirts that you are sewing from scratch!

Cut your shirt a little bit longer than you want it to be. How much longer you cut it depends on the width of your bias tape. This will typically be about ½ inch (1.27 centimeters).

Unfold one edge of the tape, and pin it to the bottom edge of your shirt. Make sure that you are pinning the right side of the bias tape to the right side of the shirt. You will eventually be folding the bias tape inside the shirt. Leave about 1 inch (2.54 centimeters) of extra bias tape to either side of the shirt.

Sew the bias tape to your shirt using a straight stitch. Use the crease along the bottom fold of the bias tape as a guide.

Fold the bias tape to the inside of your shirt. Fold the bias tape down first, then fold it inside your shirt. The raw edges should now be under the bias tape. The bias tape also should not be visible from the outside. The seam between the bias tape and the shirt will be right along the bottom edge of the shirt.

Press the hem flat with an iron. Use a heat setting that is suitable for the material you are working with. Each fabric will require a different heat setting.

Tuck the excess bias tape into the hem, and press it flat with an iron. If you'd like, you can clip the corner of the bias tape first to reduce bulk.

Secure everything in place with sewing pins, then sew the bias tape down using a straight stitch. Sew with the inside of the shirt facing you, so that you can get as close to the top edge of the bias tape as possible. Use a bobbin thread that matches your shirt color, and a sewing thread that matches your bias tape color. Remember to sew back and forth a few times at the start and end of the shirt. Pull out the pins as you go.

Give the shirt hem a final press, and snip off any excess or loose threads. Your shirt is now ready to wear!
