This is the standard single ply with adhesive applied to both sides. It is approximately 42 inches wide (107cm), coarsely woven, double stiffened 100% cotton, resembling needlework template, 18-24 thread count per inch, slightly smaller openings than the old US made foundation. Use for flat pattern hats requiring sturdy frame foundation. Also can be blocked as a hat frame before covering with fashion fabric. This product will be provided in a continuous length unless our remaining stock restricts us from doing so. We do give extra to compensate for splicing. If one continuous piece required please tell us. We will try to accommodate your needs. Using mulling fabric over the buckram frame will aid in softening the harsh lines of the foundation.
