It is ideal for situations where buckram would be too bulky or might buckle from moisture (such as perspiration) or as an interfacing for translucent hats. Ny-buck is an ideal choice for flat-patterned hats for theatre and for the re-enactor. It can easily replace wire framing as a faster solution. It will also block. We set the blocked shape with heat and find it holds well. Ny-buck will tint with acid dyes or household dyes with vinegar added. While it will not dye a deep color, it will dye into softer pastel colors. Ny-buck should only be pressed with an iron set for nylon/synthetics. Too hot of an iron setting can scorch or shrink the material. Seams in this material require top stitching to lie flat, as they may not iron out completely. A 36-40 thread count per inch.
Nybuck is waterproof. Wonderful to use for large brimmed hats for out-of-doors events.
