I could physically never baste or pin a quilt on the floor as I would have to sit and wait for someone to help me get up. I do have a long, narrow piece of plywood which I put on my ironing board to spread out the quilt in order to baste it. I have also hung my quilts to be against the wall so that I can baste them; this is very challenging to do, as you can imagine, but I have had to do it in some places I have lived. I have also used a plastic quilting frame to hold the quilt taut while I worked. I would suggest you look around your house and envision how you might solve your problem. Please write back and let us know your solution, as that may provide a solution to a similar problem for someone else. Happy quilting!
