Make a sandwich and practice on it. The more you do it the easier it becomes. I've done MQ with just a walking foot, there are a lot of continuous designs that if you go slow you can accomplish this. FMQ does have a larger learning curve and patience requirement.
I don't know if there's one quilt I've done that hasn't tried my patience at some point or another. I've learned that if I'm getting frustrated, put it away and come back to it. Sometimes that break clears the mud and I get back to enjoying. If I don't enjoy its WORK and that's nooo fun!!
:-D :-D
