Since DH gets very nervous if I try to tackle the basement stairs, he set up a work area for me out in the garage. He had a table set up,and covered, had all of my tools available, and took my IV pole out to hang the pieces on before and after they were done.
This set up was also the best we could devise for actually cutting the batting to size. It turned out to be a bit like solving a jig saw puzzle, but finally they all had a piece of batting and it was time to spray.
Then, one at a time, each was sprayed, very carefully, and, yes, I wear a fine particle respirator when I use basting spray.
This was actually a big job, and I had to sit regularly ( That's why the stool is right beside me) We have been planning it for over a month. Afterward, once everything was cleared away, I celebrated by making a batch of blueberry muffins. So-o-o good!
