Threads and fabrics are the two most common and important elements in all types of sewing. In fabricating soft furnishings for the home, it is necessary for a good finished product to use elements that are suited for the application.
Let’s talk about thread. Using the correct thread can be the difference between success and failure. We wouldn’t use upholstery thread for sheers or a fine hand sewing thread for slipcovers. Therefore, it is important to know the correct size or weight of thread to use for each item to be sewn.
What is thread weight? We all see those numbers next to the thread name. Did you ever wonder what those numbers mean? Thread is weighed or measured in 5 different ways: Weight (WT), Denier (Td or d), Tex (T), Number, and Composition.
Weight is a length measurement and is determined by measuring the length of one gram of thread. If one gram of thread is 30 meters long then it is 30 weight thread. The higher the number the finer the thread.
Denier is also a thread length measurement and is the weight of 9000 meters of thread. The larger the denier number, the heavier the thread.
Tex is the most consistent of the thread measurement systems. It measures 1000 meters of thread in grams. One thousand meters of thread that weighs one gram is 1Tex. The higher the Tex number the thicker the thread.
The Number System was developed in Japan and is called the Gunze Count system. It is used on finer thread and should not be confused with a weight measurement. It is designated as No. 50 or #50 for example. The smaller the number the heavier the thread is.
The Composition Standard was developed for cotton thread but has also been used for polyester. This can be confusing because a cotton thread and a polyester thread with the similar numbers aren’t always exactly the same. Compare cotton to cotton and polyester to polyester. Let’s look at a 30/3 thread. The first number is the same as the Number System explained above. The second number is the number of plies of thread twisted together. For our example, a 30/3 thread is a No. 30 thread with 3 plies twisted together.
So now that we know what those numbers mean, selecting the correct thread for the job is based on more than just guess work. With this knowledge we can also compare different threads for the qualities we need knowing that the job will go easier with the correct thread. Knowledge saves us time and money.
Pattern repeats are everywhere we look. They are on our clothing, wallpaper, furniture, household items, rugs, dishes, home décor and fabrics just to mention a few.
They are very important to a soft furnishings fabrication business because pattern placement is crucial to achieve a well made pleasing product. On a pair of drapery panels, that basket of flowers should be at the same place along the top of both panels so that the repeat flows across the panels in the same place. The same goes for cushions – all cushions should have uniform repeat placement.
So what are pattern repeats exactly? A pattern repeat is a designed motif that is repeated in regular intervals over an entire item. It’s as simple as that…sort of.
How is a pattern repeat measured? A pattern repeat is the entire motif with a bit of background and not just the basket of flowers by itself. The repeat is measured from the exact point on one motif to the exact point on the next repeat. Let’s say that we pick the top of the topmost flower as the starting point for our repeat. The repeat is measured from that one point down to the exact point on the repeat below it. (Or above if we are measuring up.) You can pick any spot on the repeat as long as you go to the exact same spot on the next repeat. Pattern repeats are measured both vertically and horizontally and the horizontal repeat is measured in the same way as a vertical repeat.

Ever get confused when the workroom or installer asks you what the hardware return is? Or what projection do you want on that valance?
Projection and return are two different things. The best way to explain it is this way. Projection is going from the wall out. Return is going back to the wall.
Drapery hardware projection and return are shown in the diagram above. As you can see, the projection is the whole bracket measurement from the back of the bracket to the front. The return is measured from the middle of the rod back to the wall.
Fabric returns back to the wall. For drapery panels the return is the fabric on the panel side that folds back to the wall and blocks the light on the sides.
Boards and hardware project out from the wall. For board mounted window treatments, the projection is depth of the board. The return is the fabric that is on the sides of the board mounted window treatments.
Shutters and binds project out from the window.
Knowing the difference comes in to play when ordering hardware or specifying a valance that has to clear shutters or blinds.Here’s an example of what can happen if you don’t understand these terms.
A designer specified drapery hardware for a window with existing shutters. At the measuring appointment the workroom was told by the designer what the bracket return should be. Panels were fabricated with the return measurement that was given. But when ordering the drapery hardware, the designer thought that the bracket projection and return measurements were interchangeable. At the install, she was shocked to see that the bracket return was much too small for the panels to hang clear of the shutters. The panels would not clear the shutters and thus laid over the top of them.

One part of our job as window treatment professionals is to calculate the correct yardage for traversing drapery panels. These calculations involve several steps.
First exact measurements of the window must be taken correctly and in all of the right places. Be sure to use a measuring sheet so that you will not forget any important information.
Secondly, the finished width, finished length and fullness are determined. This information will need to be discussed with the homeowner and/or designer to make sure the drapery will cover the area desired. (We will be using the measurement for the whole window width plus the amount of wall to be covered on each side.)
Thirdly, we need to know what fabric and linings will be used. Does the fabric have a repeat?
After this information is gathered, we are ready make our calculations.
- Multiply the finished width by the fullness amount and add 27”. Then divide this number by 54” to find out how many widths of fabric are needed.
- Add the hem and header measurements to the finished length to get the cut length.
- Divide the cut length by the fabric vertical repeat to find out how many repeats it will take to make up one cut length.
- Multiply the vertical repeat by the number of repeats to arrive at the total cut length. This will be longer than the cut length. Round up this number.
- Multiply the number of widths needed by the total cut length. Divide by 36” for the number of yards needed for the whole window.
Once the face fabric yardage has been calculated you must also calculate the lining yardage using the same method.
Want an easier, faster, and accurate way to calculate traversing panel drapery yardage?
Seamless Workroom Traversing Panel Workbook will do all of this and more for you. As fast as you can type in the basic information, the workbook will calculate your fabric and lining yardages and pricing, trim pricing and yardage, banding yardage, labor costs, hardware costs, miscellaneous costs and sales tax for you.
