ok here goes what i figured
strips inches needed
red and #1 1 1/2 inch strips 6 = 9

#2&#3 9=13.5
#4&#5 12=18
#6&#7 16=24
#8&#9 19=28.5
10&11 23=34.5
12&13 26=39
14&15 29=43.5
#16 33=49.5
this does not allow for any extra i would buy at a min. at least 1.5 to 3 inches extra on each

this does not come out the same way i posted it but it give the number of strips needed and how many inches to buy
