A seam roller is one of my favorite tools. It lets me press right at the sewing machine and I never have to wait for it to heat up (like my iron), so it speeds up my sewing a lot. It’s also a “green” way to save the environment and save money on my electric bill.
Here’s how to properly hold your seam roller:
YES: Hold the seam roller with your fist, with the handle straight up-and-down. This reduces pressure on your wrist and keeps the joint between the handle and the head of the seam roller from loosening. Your arm is in an ergonomically correct position and the weight of your arm provides most of the pressure without having to press down very hard.
NO: Holding the seam roller at an angle will, over time, cause the joint between the handle and the head to loosen. You have to press harder to get a sharp crease, putting pressure on your wrist, and this might cause you to develop wrist pain.
