Pick stitch in sewing refers to a simple running stitch that catches only a few threads of the fabric, showing very little of the thread on the right side (outer side) of the garment.
A pick stitch can be made from either the inside of the garment, or the outside, depending upon how much thread is meant to show on the outside of the garment. A pick stitch is commonly used for making hems, although it is also used with contrasting thread to create a decorative finish on some garments. It has decorative uses in embroidery.
A finely-made pick stitch is difficult to accomplish, and can be achieved only with practice. A pick stitch along the outside of a lapel is a hallmark of a "high-end, hand-made" men's suit or blazer.
