How many double rubs do I really need?
Here is an article that can help you decide.
Pressed cane is can that is made in sheets using a machine. The cane is then cut to size to fit the chair, and pressed into a groove that follows the perimeter of the opening, instead of drilled holes. The cane is then held in place with reed spline, and glue. This technique looks similar to hand caning in pattern, (and also comes in many variations), but the cane sits in a groove, rather than being woven through a series of holes in the frame.
Cushions are not a one style fits all. The cushions on the left are referred to as 'knife edge cushion', and they have a single seam around the perimeter. Knife edge cushions are usually 1" - 2" thick, and are found on chair seats. The blue cushion on the right is a 'boxed' cushion. It has two seams, and a boxing that create a frame for more formal and thicker cushions. Boxed cushion are found on large pieces of furniture, and large window seats.
Strand, or hand caning, is the most well known of the seat weaving designs and patterns. The pattern is accomplished through a seven step procedure that requires the weaving of individual strands of cane through holes drilled in the perimeter of the seat. This is a very tedious, and time consuming process, but will create a strong and durable pattern when completed.
