Hi Colleen -- I FMQ exclusively on my 301A because I don't have anything else to use. My 301A is not dropped down into the table so I made some portable 'tables' that slide next to the machine. Also, I use a large piece of tablecloth plastic to cover over the machine bed and cut a hole out for the needle. I drop the feed dogs and keep my tension set at about 3-4. My tension will drop to 0 if I don't watch it. Then it's just a matter of taking my time and getting my stitch length even. I have stitched up to a lap size quilt in it. Also, make sure to change the needle and dust out the machine to help with the stitch quality.
I have a large t-shirt quilt ready to quilt this weekend, but I think I'm going to tie it rather than quilt it since it's going to a college bound boy and he probably would rather have it tied.
Good luck with your machine...I love mine.
