Unit of Measure	inches	cm
A. Finished Width (?) Intended width of finished cushion. Foam or filler should be oversized by 1% or a minimum of 1/2 inch (1.3 cm). Thus, the foam width will be at least 1/2 inch greater than this measurement and, for wider cushions, 1% of length greater. Close		{{data.UofM}}
B. Finished Length (?) Intended length of finished cushion. Foam or filler should be oversized by 1% or a minimum of 1/2 inch (1.3 cm). Thus, the foam length will be at least 1/2 inch greater than this measurement and, for longer cushions, 1% of length greater. Close	Decimals!	{{data.UofM}}
C. Thickness (?) Foam or filler thickness without compression. Close	Decimals!	{{data.UofM}}
Quantity (?) Total number of cushions needed with these dimensions. Close	Integer!
Fabric Width (?) Useable fabric width -- sometimes called nominal width (often 46, 54, or 60 inches -- 116.8, 137.2, and 152.4 cm) Close	Numbers!	{{data.UofM}}

Include in Rendition: (?) The "Full Cover" means you will use the fabric for the top plate, the bottom plate and the boxing on the sides of the cushion. The "Plate and Boxing" means you will use the fabric for the top plate and the boxing on the sides. “One Plate” is only the bottom plate fabric of the cushion. Close

--OPTIONAL PIPING--
Prefabricated Piping = {{data.binding}} {{data.UofM}}
OR, for Straight Cut 1.5 inch (3.81 cm) piping (cutting along the width of the fabric) = add {{data.bindingStraight}} {{data.UofM}} of additional fabric.
OR, for Bias Cut 1.5 inch (3.81 cm) Piping, add approximately {{data.bindingSource}} {{data.UofM}}.
