How to Make Lined S Wave Curtains

This easy step by step guide with pictures shows how to make lined S wave curtains at home. These are simple to make and using a separate lining opens up a wider range of decorator fabrics you can choose from for your curtains.

Making Curtains From Patterned Material

When using material with a beautiful pattern it is important to buy more material than you need so that you will have enough to line up the patterns on each panel.

Look at how far along the length of the material it takes for the pattern to repeat itself. Then buy that length extra on top of the amount required.

When you begin to make the curtains remember to line the fabric up when cutting out the two panels so the pattern matches across the  width of the panels.

If they don’t quite match up after cutting then you can either reduce or increase the hem on the top or bottom of the panels to get it right.

Creating S Wave Curtains

What are S wave curtains?

S wave curtains are flat curtains without pleats which form an s shape or wave when hung on the curtain rod.

Why do you need to line curtains?

Using a thermal lining on the back of curtains will prevent the cold from coming in the windows in the winter and keep the heat out in the summer reducing heating and cooling costs.

What is the best lining for curtains?

Three pass or triple weave curtain lining with thermal block out coating will provide the best insulation for your windows.

How far apart do you place the rings for S wave curtains?

The rings for S wave curtains should be between 4 to 6 inches (10 to 15 cm) apart. To work out how many you need divide the total width of the curtain fabric by how far you would apart you would like the rings to be then add 2 rings.

Working Out Fabric Quantities


To work out the length of each curtain; first measure from the bottom of the curtain rod to the top of the kick board then add at least 4 inches (10 cm) for the top and bottom hem.

You may wish to have a wider hem at the top and bottom or you may want the curtain to finish below the top of the kick board so the length is purely up to personal choice.

As you will need 2 curtains simply times the length by 2 to get your final length of fabric needed.


To work out the width of each curtain measure the length of the curtain rod then halve that number. Add on 4 inches (10 cm) for the side hems.

This measurement will mean the curtain panels will be flat across when closed which is a good option when you would like to see the pattern on the fabric.

To keep a wave in the curtains when closed; times the width amount by 1½. Keep in mind the widest curtain material is usually 5 Foot (150 cm) wide.


The lining amount will be the same as the decorator fabric. Triple weave or 3 pass with thermal coating is the best however it is more expensive. Remember any lining is better than none. It is always a good idea to check the reviews before purchasing.

How to make lined S wave curtains at home.

  1. Cut Out the Decorator Fabric

    First iron the decorator fabric to the manufacturers directions then lay out on the floor with the print side down. Measure the length and width needed using a pen, pencil or pins to mark the measurements then cut out the two curtain panels. Remember to make sure the pattern lines up across the two panels.

  2. Iron the First Hem

    Fold the edges of the decorator fabric under ¼ inch (5 mm) then iron flat. If you are not confident doing this by sight simply measure and pin the hem first.

  4. Cut Out the Lining

    Iron the lining making sure you don’t iron the side with the thermal coating. Lay out on top of the curtain fabric with the thermal coating facing up. Smooth out the lining flat then cut 1 to 2 inches smaller than each side depending on how wide you would like your hems to be.

  5. Pin the Final Hem

    Fold the edges of the decorator fabric over the edge of the lining then pin.

  6. Iron the Hem

    Take care to line up the corners evenly. Check the length and width measurements to make sure they are correct and also make sure the patterns are still lining up between the two panels. Carefully iron the edge of the decorator fabric without touching the lining with the iron.
