The practical bias binding makers from Prym allow for the perfect shaping of bias strips of any length for trimming any fabric edges or patchwork quilts. By cutting the fabric strips at a 45-degree angle to the grain of the fabric, the bias binding becomes elastic and can be perfectly processed even in curves. Once the fabric strips are cut and connected, the fabric is inserted into the wide opening of the bias binding maker and pulled through. The perfectly folded bias strip can be pulled out from the flat side of this handy helper and smoothed directly with an iron. This way, the bias binding is created quickly and reliably, and can be easily rolled up for further use.
