There is a thin silicone beading sewn neatly around the edges of the print that fits into the front of the framing. Once inserted, the fabric print stretches tight and is perfectly flat. The process is so easy that prints can be removed and swapped from the frame in minutes, without the risk of damage. All frames are made with a sturdy aluminum and are easy to assemble and disassemble for storage purposes.
