The foundation of an overcast bar consists of two or more threads of the material left after removing the warp and/or weft threads. Overcast stitch is then closely worked over the threads, keeping the stitches close and firm in order to produce a neat, rounded bar. This type of stitching is used in Italian cutwork.
Also known as: corded bar, twisted bar, whipped bar stitch, wrapped bar stitch
