There are times when you just can’t see what you are doing. Maybe you are just trying to thread a needle or there is a tricky part of what you are sewing that you just can’t see well. This very small distortion free 3x magnifier solves the problem. Using the included hook and loop tape, the magnifier can be attached directly to your sewing machine. Because it affixes with self adhesive hook and loop tape, it is easy to reposition and even move from machine to machine. A very useful notion to add to your sewing toolbox.
