New booth design

Starting work today on my new booth. I purchased 6 of these beautiful natural cotton drop clothes from Lowe's. After pre washing them they shrank an average of 3" in both directions. Need to keep this in mind moving forward. Originally I was going to see them together to make a 6'x10' pillowcase etc. however since they are now shorter than my propanels I think it will be best to use the 9' side running up and down and seam another piece to make up the width. I could have bought larger drop clothes but I don't like having to deal with so much stiff fabric. We shall see if My logic holds or if I should have bought bigger.
