At a glance, Coton a Broder might look a lot like regular DMC embroidery floss, but it’s not at all the same thread. It’s made out of cotton and it’s skeined the same way as floss, but that’s where the similarities end. Coton a Broder comes in various weights (or thicknesses), and these are indicated by number. On the label above, you can see No. 25, indicating the thickness of the thread. Like wire, the higher the number, the finer the thread. DMC Coton a Broder comes in other sizes – from No. 16 up to No. 30 – but No. 25 is perhaps the most popular size.
