If you got a thread color that would blend your mistakes would not show. I just took my first class and got certified. Went back one week later and got my quilt quilted It really did not take a long time to load the quilt we used the zippers for the backing so that was done at home. just zip the back on roll it up the batting and top was floated and it worked real well for me. In fact planning on going back this month would like to do one every month but that is a lot to get done in a month. I love fmq and found it easier than wrestling with a big quilt on my domestic I will still quilt on my machine for small quilts and runners but for the big ones I will use the LA . Just go and try it out.
