Do you know what selvage markings are? They may look decorative but there is fabric information contained in the markings. These markings can make planning you patchwork projects much easier.
The marks along the edge are not just branding, but can help you to pair up fabrics with that fabric that you are working with.
Examples of selvage edges
Selvage or sometimes selvedge has the name of the fabric, the line, the designer or manufacturer and a series of coloured circles. These circles make it easier to find similar shades/colours for your project to mix in with that pattern of fabric that you are using. It can be hard to see the different shades in a pattern, but the selvage makes it easier by pulling the individual shades similar to paint swatches.
So if two fabrics have the same coloured dots on their selvages they should work in well. It is also a good way to choose the solid to go with the pattern fabric.
Some people save up all their selvages for separate projects at the end.

I hope this was a little bit useful. I certainly find the information useful when trying to match colours for my projects.
