I have my mother's old Singer 301 A and I am just learning how to FMQ on it, taking all of the advice of everyone on here. The quilting on my granddaughter's quilt doesn't look all that great but it is getting better all the time. I am taking it slow and easy and I can see improvement from when I first started.
One thing I read here was to get a pair of gloves with the rubber dots on them. Wearing them makes a big difference in controlling the fabric. They were only about $3.50 at Joanns and then I used a 40% off coupon.
