Steps To Make Arched Window Curtains

So, how to make arched window curtains?

Here are the steps for you to follow:

 

Step #1. Measure it

Start measuring from above the arch towards the intended curtain length and record this number. 

Take note that the rod pocket is already included in this measurement. 

To get the width, measure the widest portion of the window. Start from the left towards the right and also record the number. 

 

Step #2. Make the pattern

After you get the measurement, you now need to create a template following the curve of the arch.  

Attach several sheets of paper using tape to create a wide enough sheet that can cover the arch.

It must be three inches longer than the length of the arch. 

Then, tape the sheet over the arch and start tracing the window casing’s outline.

Also, trace each side of the arch toward its full length. 

 

Step #3. Cut the template

Takedown the paper and lay it onto your working space.

Then, start cutting along the line you traced earlier.

 

Step #4. Divide the pattern with vertical lines

After you cut the arch pattern, draw lines vertically from the bottom edge up towards the arch.

Leave an inch of space in between every line. 

Number each section starting from the left.

Then, cut along every vertical line across the pattern. 

 

Step #5. Calculating the curtain size

Calculate for the fullness that you desire for your curtain as well as the flat fabric width. 

 

Step #6. Make an adjusted pattern

Get a paper pattern piece that is equal to the panel’s width ready.

Adjust the pattern to have a length equal to the length of the arch. 

Then, get a pencil and start marking the piece of paper for the adjusted pattern with vertical lines.

Space them evenly with two inches for every line. 

Position the first line about half an inch from the outer edge on the left. 

 

Step #7. Placing the pattern pieces

Align the first pattern to the right and tape the first piece in place.

Then, it should be followed by the second piece in the next vertical rows. 

Ensure that the left edge is aligned with the second line’s right edge. 

Repeat the same process to attach all pattern pieces you cut onto the paper with the adjusted pattern.

 

Step #8. Drawing a new arch

In this step, you need to draw another arch line right above the taped pieces of the adjusted pattern. 

Draw a curve smoothly, do not follow the lines of the taped pieces exactly because they are only placed as a guideline. 

 

Step #9. Draw the cutting line

Sketch another line about half an inch on top of the arch line. Indicate this is a cutting line, including the seam allowance. 

Now, cut onto the second line of the adjusted pattern. 

In case you intend to have ruffles on top of the curtain, add the desired ruffle depth before redrawing the cutting line. 

 

Step #10. Cutting the fabric

Following the adjusted pattern, cut the fabric as well as the lining. Ensure to add enough length that can accommodate the curtain and the hem.

 

Step #11. Sew the hemming

Sew the hems of both the fabric and the lining. 

Do thing by aligning the top of the lining and the fabric with their right sides together. Then sew again, leaving half an inch seam allowance. 

 

Step #12. Stitch the seams

Sew the lining and fabric together along the seams at the side, starting from the top down to the bottom of the seams. 

 

Step #13. Creating the rod pocket

Turn the right side of the curtain out and iron. Then sew the seam to create the curtain rod pocket.

 

Step #14. Hang the curtain

Finally, you are done making your arched window curtain. What’s left to do is to slip the rod onto the pockets and hang the curtain. 

 

Other Arched Window Treatments

Aside from curtains, you can also install the following window treatments on your arched windows. 

 

#1. Blinds

Blinds for arched windows come in different types. It is good to install this because it requires minimal maintenance. 

This is especially true if you dust or vacuum them regularly. Aside from that, blinds are also durable. 

 

#2. Valances

Valances are best paired with arched windows.

These are elegant window dressing that is designed with pleats and swags. 

The lower curve of the valance will conform to the shape of the window, thereby drawing the eyes of the people into it. 

Although this can look very formal and a bit traditional, you can use sheer or light fabric to achieve a casual look. 

 

#3. Mullions

You can add elegance to your windows without fully covering them through mullions.

These are vertical bars in between the windowpanes.
