What Is Bias Tape?

Bias tape is a specialized type of fabric trim that is made from thin strips of pre-shrunk fabric cut on the bias, which is a thread line that runs at a 45-degree angle to both the lengthwise and crosswise grain of the fabric it is made from.

Both bulk bias tape and bias tape by the yard come in a huge assortment of colors, fabrics, and styles, while contrary to its name, bias tape isn't actually sticky - there's no adhesive side. There are also different widths of bias tape including 1/4", 1/2", 1", and 1 1/2", with 1/2" being the most common size.

Different Types of Bias Tapes

Bias tape comes in two styles - single fold (with two folds) and double fold bias tape, which has three folds.

Generally speaking, double-fold bias tape is the best choice for binding an edge where both sides can be seen, such as finishing a blanket or hemming drapes.

Bulk Bias Tape vs Packaged Bias Tape

Bulk bias tape represents a great value for sewers and crafters who want to have a big project planned or often need custom-cut lengths of bias tape.

By comparison, packaged bias tape is sold in 3-yard lengths because that's the ideal size for blanket finishing. Packaged bias tapes are incredibly affordable, making it easy to stock up on a wide assortment of styles, widths, and colors.
