Tack (sewing)

Diagonal bastings

In sewing, to tack or baste is to sew quick, temporary stitches that will later be removed. Tacking is used for a variety of reasons, such as holding a seam in place until it is sewn properly, or transferring pattern markings onto the garment. Tacking is typically sewn using a specialised tacking thread, which may snap easily in order for it to be easily removed from the garment when necessary.
