Sewing curtains, or drapes as they are sometimes known, can compliment cushion making especially if you want them to match.
One way of doing this is to buy curtains that are too long for your window and then trim the excess off to get some material for your cushion. The other way is to get fabric for both. When sewing curtains a lining can be added if required, but they can also be made unlined.
However cushions and curtains don't need to match as it is good to have different colours that will compliment each other.
To begin making curtains the track or pole should be in place, the window measured , the style of curtain chosen and the amount of fabric calculated along with any curtain lining material. Once the fabric has been bought any adjustments such as pattern matching should already have been done.
Iron the material if necessary to give a smooth surface. Lay the fabric wrong side up and measure the cut length of the fabric. That is the finished length and extra material for the heading and hem. A clean floor is the best place to do this or a large work surface. Curtains need space.
Sew the lengths together to get the width for each curtain either 2 widths or 1 + 1/2 widths. Press seam.
Measure the side seams, pin and press. Turn the raw edges to the inside and sew along the turned hem
Turn the raw edges of the hem under, press and turn up hem to the required length and either machine or hand stitch in place. For full length curtains any machine sewing will not really be noticed.
The above steps for making unlined curtains can also be used for making curtain lining. Adjust the side hems so that the lining does not extend beyond the actual curtain and make the linings shorter than the curtain.
Lay the curtain wrong side up and place the lining on top right side up matching any seams or as close as possible. Different fabric widths can make this difficult. Pin the lining at the top of the curtain to then continue with the heading.
The lining can either be attached to the curtain just by the heading so the sides and bottom edge are separate or can be caught into the side hem and the bottom hem. There will be no need to hem the lining if this is wanted just lay the lining on top of the curtain and hem the sides and lower edge together.
Enjoy making your curtains.
I have tried to explain the measuring process but can be a bit confusing so have found a couple of books in Amazon to help.
