Since I have not been able to get down on the floor (well, really I can get down, getting up is the problem) I use my kitchen table for most quilts. I get my DH to help (albeit very reluctantly), I center the quilt on the table, then the batting, then the top and tape down each section with masking tape. I use cotton batting which helps the top and backing to "stick" together. I also use the large dining tables at church so I can really spread the layers out, using masking tape to keep each layer taut, then pin, pin, pin away. It really helps me to have a friend, as I have to sit and pin baste, the body is having it's revenge for not taking better care of myself when I was younger. I probably haven't given you any good advise but Good luck - you'll find a way that works best for you.
