Mid Century Sofa Bed – Upholstery fabric can be expensive. When calculating the necessary fabric to upholster a double sofa bed, the goal is to buy enough fabric, plus an additional 10 percent for accessories or future repairs. It is very useful to learn the names of the different sections of the sofa and to understand how to measure these sections. The production of sewing pieces to scale is simplified with the use of graph paper. Upholstery fabric is printed with the top of the pattern perpendicular to the selvage edge (attached), which is the long grain. This allows a long piece of fabric to be placed horizontally along the back on the inside of a sofa.
Use the graph paper and, with the same scale as a square to 6 inches, create a piece of paper representing 16 yards of fabric. Sixteen yards is a standard value of fabric for a sofa bed. If the fabric is 54 inches wide, the document will be nine squares per 96 squares. Place the pattern pieces on this “fabric”, with the width of the pieces running along the length of 96 inches. Move the patterns around so they fit on the paper with a square between each one. Count the number of squares along the long edge of the “fabric” that has been used. Multiply this number by six and divide by 36 to determine the required base footage. Add 20 percent for seams, joining, matching patterns, and future repairs.
