Threading Austrian Blinds: A Step-By-Step Guide To Success

how to thread an austrian blind

Austrian blinds are a type of window treatment that combines the functionality of a blind with the graceful look of a curtain. They are characterised by their scalloped bottom edge, which is created by pulling the blind up using a series of cords. This distinctive feature gives Austrian blinds an interesting and elegant appearance, making them a popular choice for those seeking a unique window covering.

Creating an Austrian blind from scratch can be a time-consuming process, but with the right materials and measurements, it is achievable. The first step is to measure the width and length of the window, adding a few extra centimetres or inches to ensure the fabric is scalloped even when closed. The next step is to cut the fabric and lining to the required measurements, joining multiple widths of fabric if necessary. To add a classic single frill, cut strips of ruffle fabric that are long enough to go around the sides and bottom of the blind, and stitch them together.

When assembling the blind, it is important to lay the fabric and lining flat, with the right sides facing each other. The frill is then pinned and stitched in place, ensuring that the gathers are evenly distributed. Once the frill is attached, the fabric and lining can be stitched together, leaving a small opening to turn the blind right side out. Finally, Austrian blind tape is attached to the back of the blind, and cords are threaded through to allow the blind to be raised and lowered.

Measuring the fabric

Step 1: Determine Mount Type

Before measuring, decide whether you will be using an inside or outside mount for your Austrian blind. An inside mount means the blind will hang entirely within the window frame, resulting in a neat and streamlined look. This type of mount is usually best for energy efficiency. On the other hand, an outside mount means the blind will hang outside the window opening, overlapping the edges. This type of mount is recommended for out-of-square windows or windows with minimal mounting depth or obstructions within the frame. It offers better light control and privacy.

Step 2: Measure for Inside Mount

If you've opted for an inside mount, start by measuring the depth within the frame where you'll install your brackets. This will ensure that your blind has enough space to fit properly. Next, measure the width of your window opening from edge to edge at the top, center, and bottom. Record the smallest of these three measurements to the nearest 1/8 of an inch. For height, measure from the top edge to the bottom edge on the left, center, and right. Record the largest of these three measurements to the nearest 1/8 of an inch. Inside mount blinds will have a small deduction applied by the manufacturer to ensure a precise fit.

Step 3: Measure for Outside Mount

For an outside mount, you'll be measuring the area you want the blind to cover, including any overlap. It is recommended to have an overlap of at least 1 1/2 inches on both sides of the window. Mark the spot where you want the top of your blind to be, then measure the height from that spot to the top of the window sill (or below the window opening if there is no sill). Record this measurement. For width, measure from the outer edge of the architrave to the opposite edge. Again, include any desired overlap in your measurement. Outside mount blinds will be made according to your exact specifications without any deductions.

Step 4: Tools and Tips

When measuring, always use a steel tape measure for accuracy. Record your width measurement first, followed by the height, and clearly label which is which to avoid confusion. If you're measuring for a roller blind, remember that you're measuring for bracket placement, not fabric width. Fabric width will typically be narrower than the width you provide. Additionally, if you're replacing an existing blind, simply measure the blind (including its fittings) and specify face-fitting for a perfect match.

Cutting the fabric

Measurements

First, you need to take some measurements. Measure the distance from the top of the batten to the bottom of the window, and then add 50 cm (20 inches) to this length. This extra length will ensure that the fabric is scalloped at the bottom even when the blind is closed. Next, measure the width of the batten and double this measurement to allow for fullness in the blind. These measurements will be the basis for the length and width of your fabric.

Now it's time to cut your fabric. Cut the ruffle first, following the measurements you calculated. Then, cut out the required amount of fabric and lining material for the blind itself. If your fabric isn't wide enough to cover the entire width, you may need to stitch together multiple panels to create the proper width.

Stitching

Once you have all your pieces cut, it's time to start stitching. Stitch together any panels you've had to cut to create the desired width. Press the seams open, and then join the lengths of the ruffles to make one long ruffle. Use a 6 mm (1/4 inch) seam for both the body of the blind and the ruffle. Press the seams flat on the ruffle.

Joining the fabric

To begin joining the fabric, lay the two pieces of fabric right sides together, ensuring the patterns match up. This step is crucial as it will ensure a seamless join. Pin the fabric together along the length, using plenty of pins to secure it in place. This will prevent any unwanted movement or shifting during sewing.

Using a sewing machine, set up a straight stitch with a standard length, and sew along the pinned edge, removing the pins as you go. Sew a second line of stitches approximately 5mm from the first line. This double row of stitches will add strength to the join, which is essential for the functionality of the blind. Press the seam allowances to one side, using an iron to create a crisp, neat finish. This step will ensure the fabric lies flat and the join is less visible.

For added durability, especially for heavier fabrics, consider sewing a third line of stitches down the centre between the two previous lines. This extra reinforcement will ensure the fabric can withstand the weight and tension of the blind mechanism. Finally, trim the seam allowances to reduce bulk. This will make the join less noticeable and create a more elegant finish. It is important to be careful during this trimming step to avoid accidentally cutting the stitches.

Making the ruffle

To make the ruffle for an Austrian blind, you will need to calculate the amount of fabric required. First, take the length of the blind and double it. Next, add this number to the width of the blind. Then, double this sum to get the total length of fabric required for the ruffle. Each ruffle should be around 3-4 inches in width.

Once you have cut your fabric to the required measurements, join the strips together end-to-end. Hem the bottom edge of the strip and stitch two rows of gathering stitches along the top edge. Pull the threads together until you have achieved the fabric panel width measurement.

Place the shade fabric right side up on a flat surface. Pin the ruffle's gathered edge to the edge of the fabric, approximately one inch from the edge. Ensure that the right sides touch and the hemmed edge of the ruffle points towards the inside of the panel. Continue to pin the ruffle in place, going around three edges (the top will not have the ruffle). Adjust the gathers as you go to distribute them evenly.

Stitch between the rows of thread, approximately half an inch from the raw edge. Remove the gathering stitches. Lay the shade right side up on the floor, with the ruffles facing towards the centre. Place the lining wrong side up on top of the shade fabric, ensuring the raw edges of the lining fabric match the bottom and side edges of the shade.

Pin and sew around the three edges, approximately half an inch from the edge. Press the seams flat and turn the fabric right side out.

Attaching the ruffle

Next, machine stitch the frill in place, 0.5" (12 mm) from the raw edges, between the rows of gathering stitches. Remove the gathering threads. Lay the blind, right side up, ensuring the frills face towards the centre. Place the lining, wrong side up, on top of the blind fabric, matching the raw edges along the bottom and side edges. Pin and stitch through all layers around the three edges, 0.5" (12 mm) from the raw edges. Turn the fabric right side out and press lightly.

Now, lay the blind, lining side up, and cut two lengths of Austrian blind tape slightly longer than the length of the blind. Ensure the first loop on the tape is positioned 2" (5 cm) up from the frill seam. Place the tapes vertically, alongside the frill seam on each side, ensuring the loops of the tape are aligned across the blind. Neaten the bottom edge of each tape by turning under 0.5" (12 mm). Pin and stitch the tapes in place, stitching both sides in the same direction to avoid puckering.
