I have found spray basting so much better where room is limited. I usually begin in a centre area then go outwards. At present making a reverse applique bed quilt in 12 inch blocks. I mark top and cut out . At first was tacking backing into place, with 32 blocks to do I decided to see about spray basting. I tried a nameless spray which left large dry blobs and went back to 505 which worked great. I spray the holey top lightly with 505 and then position this onto backing.
It is working great managing to do at least one block a day.
