I'm a floor crawler too. I have 12" tiles in my breakfast room. So I just stretch it across there and square up to the tiles. It is hard on the knees. I tape the back to the floor, spray, spread the batt, spray, spread the top, pin. But, I did hear of someone using two insulation foam boards to spray on. The person who mentioned this used the boards also for a design wall with the back of a flannel tablecloth on it for sticky. The spray baste, helps the vinyl stay smooth. She took the cloth off, sprayed and then reattached. Next time I am going to try that.
