Arm Covers: Arm covers are not actually part of a chair or sofa. These extra pieces of fabric are placed over the furniture’s arms to help keep them clean. Arm covers can be made from the same fabric as the furniture, or they could be a different color.
Colorway: Colorway refers to the different colors that a fabric comes in.
Deck: A deck is the portion of a piece of furniture that sits underneath the seat cushions. The deck is usually made from a solid colored fabric, and this fabric should be thick enough to prevent the interior springs and webbing from poking through.
Gimp: Gimp is trim used by upholsterers. This length of fabric, which looks a lot like a ribbon that has been braided, is commonly used to cover up the tacks that attach the upholstery to the furniture’s frame.
Nail Head Trim: A nail head trim is a series of metal embellishments on a piece of furniture that resemble tacks. These adornments can be installed individually or as a strip. Nail head trim looks particularly impressive on leather, vinyl, and upholstery that is a solid color.
Pattern Match: Pattern matching is lining up the textile’s pattern so that it appears continuous despite seams or other interruptions. It gives the furniture a nice clean look. This technique can actually minimize the visibility of upholstery seams.
Repeat: A repeat is a single, complete pattern. This term may refer to different materials, like textiles or wallpapers.
Welting: A welting is a tube of fabric with a length of thin cord in the interior. The welting is attached to the seams of furniture to conceal them and reinforce the upholstery job.
