(e.g. forepeak cushions)

Please Note:

Estimates add 1 inch (25 mm) to all boxing strips as plaque allowance.

Unit of Measurement
A. Foam Width (?)
Width of the wider cushion foam end (fabric stripes and patterns run this direction). Foam should be 1/2 inch (13 mm) larger than the finished cushion size on all sides.
   
inches
B. Foam Length (?)
Length of the cushion foam. Foam should be 1/2 inch (13 mm) larger than the finished cushion size on all sides.
   
inches
C. Thickness (?)
Thickness of cushion foam. Estimate adds 1 inch (25 mm) to boxing/plaque to allow for sewing the zipper. The extra inch should be cut down or modified during construction so the finished boxing and zipper plaque equals the thickness of the foam plus 1/2 inch (13 mm).
