The honey comb material may be acid-free paper, inert plastic such as polypropylene, or aluminum. The advantage to a honeycomb panel is that it is less flexible than foam or mat boards, particularly with larger dimensions. Fabric and polyester batting may be used to cover the board used in making a mount for textiles. These provide a cushioned surface for brittle and delicate fabrics. The recommended fabrics are unbleached, non-permanent press cotton and linen.
Silk is acceptable chemically, but it is significantly less durable than cotton or linen.
Blends, including polyester, are generally not as chemically stable for long periods as cotton and linen. Permanent press fabrics are to be avoided since they generally have chemical surface finishes that will give off potentially harmful chemicals and the process for making them may include the use of formaldehyde, a potentially harmful chemical that may not be not be entirely removable, even with repeated washing. The batting used to create a cushion should be polyester batting that is free of adhesives or other coatings. This is often available in stores selling supplies for quilt making. The method used to mount a textile for framing will have a significant influence on how well an item is preserved and retains its shape while hanging in a vertical position within a frame.
