Past Participle: unstitched
Unstitch → It is formed from "un-" (meaning not or to reverse) and "stitch" (from Old English "sticca", meaning to pierce or to sew). The word "unstitch" means to reverse the action of stitching, or to take stitches out.
Think of 'un-' meaning to reverse something, and 'stitch' referring to sewing. So, when you unstitch, you are reversing the sewing process.
