How to make curtains longer

I love my Ikea Sanela curtains, but even at 118″ inches long, they were just too short for my tall windows. Since two-story custom curtains cost an arm and a leg, they were just not in the budget for me.  I had to brain storm more reasonable DIY options to make them fit.

Below is a step-by-step guide how you can elongate your curtains to a custom fit, but at a reasonable price tag.


You don’t have to be a great seamstress to elongate your curtains, but you will need a sewing machine. I used the following materials:

  • Sewing Machine
  • Curtain Material (I bought an extra panel from Ikea)
  • Matching Thread
  • Sissors, pins, iron, ironing board

I was disappointed to find that most tutorials on the internet had you join a different pattern to the curtains. This was not the look I wanted. My aim was to create seamless continuous look, as if I paid big bucks for custom curtains.

To achieve this, I bought an extra set of curtain panels to use as the extra material. Because Ikea’s curtains are so affordable, it was still way cheaper than ordering custom curtains, that’s for sure. Final price tag: $140

Here’s how I did it:


Step 1: Hang curtains and measure. I like to hang the curtains first to get an accurate measure of how much material to add.

First, measure the amount of material you would like to add from the end of the curtains to the floor. Let’s call this the desired distance. For me, this was 15 inches.


Step 2: Calculate how much material to cut. I doubled the desired distance so I could fold the material in half and sew it to the bottom of the curtain panel. Then I added 1 inch for the seam allowance.  My total length to cut was 31 inches:


How much material to cut? Double your desired amount and add a 1″ seam allowance:
 (? inches x 2) + 1 inch

 Step 3: Cut your material.

31inchesCut the material the calculated amount.

Step 3. Crease a 1/2 inch fold to hide the frayed edge.  Use a hot iron and fold over a 1/2″ on the top and bottom of your material. When you sew, this will make a neat edge and hide your frayed edge.


Step 4: Fold the extra material in half and pin onto the bottom of your existing curtain:

I had to do this on the floor. This is what it looks like:

Step 5: Sew the extra material onto your existing panel.


I sewed the curtains together straight across using a 1/4″ seam:

 I was able to achieve my goal of creating custom-fit curtains at an affordable price.


I think the addition looks like a tall hem on the curtains, like it was supposed to be that way.



Go, You!

I hope you found this useful :)
