It is the fastest and most efficient way to prevent fabric edges from fraying. The disadvantage is that the material has to be sturdy enough for the seam not to come undone after washing.
For this machining method, the fabric is reverted and stitched with a simple seam. This method is far more stable and visually pleasing than an overlock seam. The use of narrow seams is predominant for curtain sides.
The high or broad seam (starting at 3 cm) has the advantage that a lead band can be added, which makes the curtain fall nicely. Broad seams are mainly used for the bottom edge of a curtain.
The reverted fabric of a double seam reaches the bottom edge of the seam. This results in a visually pleasing effect, especially when using transparent curtain fabrics (like a voile).
In addition, the shrinkage caused by washing can be compensated for by unpicking and "letting out" the fabric.
The double seam is used for the bottom edge of curtains.
The only difference between broad seams and pocket hems is that a pocket seam is open at the ends, whereas a broad seam is closed at the ends. This is a small but important difference, which will be an issue when you want to put a pole in, but the curtain has a broad seam, not a pocket hem.
This type of hem is used to keep textiles flat, stretched out and down to the floor, without any gaps.
This method excludes gaps of light under a stretched cyclorama.
An eyelet clamping bar works just like an invisible pocket hem. It is used to keep fabrics stretched flat and down to the floor, to prevent light coming through gaps. This method is primarily used in TV-studios to stretch cycloramas.
A train is predominantly used for main curtains. It compensates uneven floors and prevents an ugly gap of light between the main curtain and the floor.
Wear-and-tear is taken into account when trains are used. These are eventually replaced by new trains (usually after years).
One method is to sew the belt on to the reverted fabric. This only requires one seam and the belt is invisible from both sides. This method of reinforcement requires more fabric than a belt with double stitching.
The belt is attached with two seams. Since only the selvedge is reverted, this method does not require much fabric.
The welt originates from tent building and sailing, where fastenings with welts and their fitting profiles are commonly used. Welts can hold incredible tractive forces. This allows a relatively smooth exchange and materials can be stretched flat evenly.
As long as there is tension on the material on the welt, it remains firmly attached and can’t be moved. Suitable mechanisms for moving the welt profile are necessary, if the material is to be stretched flat. Welts are mainly used outdoors or for trade show booth construction.
Velcro is often the perfect solution for assembling or disassembling textiles quickly and easily.
Velcro sometimes has a bad reputation in regard to adhesive strength and durability. This is often due to cheap products, that don’t cling after having being used two or three times.
