My suggestion is to tear 2 pieces 88" long, then you will still have 58" left.
From that 58" cut a piece about 45" long and then split that down the middle so that you have 2 pieces of aprox 21x45. Sew those two together so you have one pieced section of 88 x 21. Sew that section between the two whole sections of 88 x 44. Give or take a few inches depending on the width of your fabrics.
Hope this helps
