When I do industrial sewing, I not only need an industrial sewing machine but also other tools.
This is a 7 feet (182 cm) ruler. Before I found this ruler online, I was using a 4 feet ruler. The width of the fabric is about 60 inches, so a 4 feet ruler was not enough to go across the width of the fabric. I had to be creative when I drew a straight line to cut the fabric then. But with the 7 feet ruler, which goes right over the width of the fabric, it makes it a breeze to mark the fabric for cutting. It was such a good tool to buy: I use it all the time for a large job.
Also, a pair of very sharp scissors is a must as well. I have a sharpening machine to keep the scissors very sharp.
