I've come to believe that my migraines are caused by eye strain. I just ordered a larger computer monitor and I'm researching magnifiers for my sewing machine. The biggest one is called C.C. Bigger that clamps to your machine. Then there's MagniStitch with adhesvie to stick to the machine and another gooseneck thing that clamps to the front of the table. anybody with experience with these magnifiers? Do they really not interfere with sewing, esp FMQ?
