Curtain Hem Step-by-Step Guide

Here are the step-by-step instructions for hemming curtains to the exact length you need.

Step 1: Measure the Length of Your Curtains

In order to hem your long curtains, the first step is to measure the length of the curtains. With your curtains hanging, measure from the top of the curtain rod or curtain rings to the desired length. Make sure to measure carefully, as this will determine the final length of your curtains.

  • Tip: Use a tape measure to find the dimensions of your curtains and mark your desired length with a fabric pen or tailor’s chalk.

Step 2: Cut the Fabric

Cut the fabric to the length you want, leaving an extra inch or two to allow for the double-folded hem.

Step 3: Fold the Fabric

Fold the bottom of the curtain towards the back of the panel to create a hem. Make sure the hem is in an even, straight line. Then, fold it under once more to the desired depth of the hem. This second fold is crucial as it will hide the raw edge and give your curtain a smooth finish that won't unravel.

Step 4: Iron the Hem

Use an iron to press the hem in place along your ironing board, making sure the fabric is even and without any creases. This step is particularly important if you are dealing with thick fabric.

Step 5: Pin the Hem

Use straight pins to hold the hem in place. Make sure the pins have equal spacing between them, so the hem stays in place. If you are using hemming tape, which allows you to hem curtains without sewing, skip this step

Step 6: Sew the Hem / Glue the Hem

Using a needle and thread or a sewing machine, sew along the bottom edge of the hem to secure it. For professional-looking curtain hems, sew along the edge of the fabric, making sure the stitch is straight and that it matches the original stitch length. 

If you are using the no-sew method, apply iron-on hem tape along the edge. Feel free to trim the tape if you have a narrower hem. Once the fusible tape is in place, slowly iron it on, ensuring the heat properly activates the glue. Note that if you have sheer curtains, however, it is best to use the sewing method.

  • Tip: If you are sewing your hem, use a matching or invisible thread for sewing, so the hem is discrete and does not detract from the overall appearance of the curtains.

Step 7: Repeat the Process

Repeat the process for the second curtain panel, if you have a panel pair.

Step 8: Hang the Curtains

Once the hems are complete and your curtains are the perfect length, put the curtains back up on your curtain rods and check to make sure they hang correctly and are the exact length you want.
