I live in a small cottage and quilt in my caravan when I go travelling. Both of these have very small floor spaces. I use the method mentioned above it is great.
I also tend to do quilt as you go so I only use small squares to sandwich at a time. Problem comes when joining them all but done it sections even makes that possible the final long seam is the biggest and heaviest problem.
I must admit I use 505 to do my blocks sometimes. .
