I can only suggest that you find somewhere that you can baste a quilt without getting on the floor. Is there a LQS, a friend, a church or a library or senior center where there would be banquet tables (dark brown ones that fold up found at office supply stores) that you could use???
I use to go to my then LQS and use the classroom when it was available. It was so enjoyable spending time in the quilt store taking breaks occasionally looking at the new fabric, samples and patterns. It made for an enjoyable day.
