A Stitch on TikTok is another way to repost a video, which is similar to a Duet but with each clip getting its own screen time. To use this feature, click on the "Share" arrow of the video you'd like to stitch and then click on the "Stitch" button from the pop-up menu. Choose 5 seconds of the video and then post the Stitch, which will also include the original creator's username in the caption as attribution.
