You will come across some of the most manageable steps for sewing the corner and will not experience any problems during the process. 

How To Sew A Corner Hem

When it comes to sewing a corner hem, there are two ways you can do so. Both of these ways have simple steps that you need to follow. To know what they are, check the information below. 

Equal Hem Depths

Step 1: Fold and press on the side hem.

Step 2: Fold and press on the next side of the hem. The second or the bottom hem will overlap with the side or the first hem right at the corner. 

Step 3: Fold and press the side one more time but by 1 inch. After that, fold and press the side or bottom hem again but by 1 inch. The hems will overlap right at the corner. 

Step 4: Unfold both the hems to reveal all the pressed lines. The place where all the pressed lines intersect will be an area where you will start sewing the corner hem.

Step5: On the intersection, fold the fabric’s right sides together at a point, which should, in return, form a triangle. After that, put a pin at a 45-degree angle right from the intersection, and it should point towards the raw edge.

Step 6: Opt for a straight stitch and start sewing from the pinpoint right at the folded edge towards the first pressed line.

Step 7: Lock up the stitch at the end and the beginning.

Step 8: Try trimming out the excess triangle to ¼ right from the sewn seam. 

Step 9: To receive an additional smooth angle, try to trim away right from the folded edge till the right side of the seam. 

Step 10: Press the open seam.

Step 11: Close the hem back into its place while pushing out the corner hem. Once it’s done, pin the folded edges. 

Step 12: You can sew with a decorative stitch that you like or go for the straight stitch, close towards the inside folds. 

Unequal hem depths

Step 1: Fold and press on the hem for ¼ inch.

Step 2: Close and press the hem located at the bottom for ¼ inch. The bottom hem will overlap with the side hem. 

Step 3: Close and press the side hem for 1 inch. 

Step 4: Fold and press the bottom hem for 3 inches.

Step 5: With a pen or a colored pencil, try marking the areas where the two hems meet. 

Step 6: To expose the pressed lines and marked points, unfold the hem. 

Step 7: Close and pinch the fabrics on the right sides together and make a fold line, which runs through the intersection points shown by the pressed lines. Using an iron to press on that place to smooth out the area. 

Step 8: Refold all the raw edges for ¼ inch while following the actual pressed lines. 

Step 9: Close the corners towards the insides of the intersection. Doing so, you will find that the top fold edge is perpendicular towards the pressed or drawn lines, which you have made.  

Step 10: Beginning from the side hem, fold in the fabric at an angle to meet with the marked points and place a pin on that area. Make sure to keep doing it several times to make the right fold.

Step 11: Fold the bottom hem in a way so that it meets the marked points perfectly and makes a mitered angle. Once the folding is done, put a pin on that place.

Step 12: With such a colossal miter, you must hand-stitch the miter so that it will help in holding the angles within its place. 

Step 13: Like the equal hem depths, you can either choose a decorative stitch of your choice or opt for the straight stitch. You must sew along the folded sides to secure the area and complete the entire stitching work. 

Difference Between Equal And Unequal Hem Depths

Although the unequal and equal hem depths have similar sewing techniques and methods, there is a slight difference between the two. 

Under equal hem depths, you need to transform all the raw edges into small measurements, such as ¼ inch to S/S inch. After that, you have to turn the hem under the set measurement to obtain your finished length. 

However, the second measurement is larger or equal to the first measurement. 

The unequal hem depths, the unequal one is a bit trickier and will take a bit of fussing to make sure the corner hem is done right. 

If you try to hem the corner of a drapery panel, you will find the bottom hem is a lot deeper than the side hem. The bottom hem and side hem should be 3 inches and ¼ inch, respectively. 

Finishing Option For The Raw Edges

You can quickly transform the raw edges of the fabric with the hem in a hassle-free manner. But you are free to finish off the raw edges before starting with the hem work. 

You can opt for the zig-zag stitch on the sewing machine. Otherwise, you can use the overlock stitch on the serger. But doing the work on the serger will be a good idea because it delivers a clean and smooth design.

Rather than finishing the edges first, the other remaining steps are the same. You can utilize the serging as a guideline to sew around the hem when the corner hem is completed. 

Tools And Materials Required For The Sewing Work

When it comes to sewing the corner hem, you do not need many items to get the job done. The only thing you must have is the fabric you like, or you can also choose softened medium-weight linen. 

Other things you need are a thread that will match perfectly with your fabric, sewing machine or a serger, scissors, point turner, needle, and fabric marker. It would help if you also had pins, a ruler, and a sewing gauge for the sewing work.

When Exactly Must You Sew A Corner Hem?

There are several places where you can sew the corner hem to deliver a clean look. Here are some of the areas. Look below!

Panel Curtains

You will find corner hems located at the bottom corner edges at the panel curtains or any window treatment. 

When the curtain is lined, the lining gets sewed separately and is pretty short than the hemline. So, it will not interfere with the corner hem technique. 

Table linens

Napkins, placemats, or tablecloths are table linens, which get sewn with one single fabric. With a corner hem, it will eliminate the presence of a bulk that occurs within the corners. 

This will help in the function of the finished product and improve the appearance or look of the item. 

Garments

Garments, such as coats, aprons, and skirts also have corner hems. These corner hems are also pretty visible on these garments. Apart from that, clothes made from wool or other heavy fabric will have corner hems. 

When the garment or the clothing has a lining, you will find that the lining has unsewn edges. These edges get hand-tacked right back to their place after completing the corner hems. 

Quilt bindings

Quilt bindings stand out as one of the most popular products in the market that have visible corner hems. The main reason to provide corner hems is to terminate the bulk.

Also, sewing the corner hems has been a favorite technique among all the quilters in the market. It’s because the process enables them to create beautiful bindings. 

Do You Need To Press Or Iron The Fabric After Sewing?

In short, yes, it’s compulsory. Pressing or ironing stands out as one of the crucial elements of sewing techniques, especially for corner hem. You can rely on the press lines as they will tell you to stop and start sewing. 

The press lines can also tell you where you need to make a mitered line within an unequal hem allowance. You have to be flawless when you are pressing if you want the points of the intersection to be as accurate as possible. 

Additionally, when you are utilizing a bulk fabric, you have to be careful when pressing on them. Don’t try to make a pressing imprint on the fabric’s right side. 

Try placing a cardboard piece, metal hem gauge, or heavy paper between the fabric and the hem. Doing so will prevent imprinting from occurring.
