Using the Lee Products Yellow Highlighter Tape is super easy. First, when you're working on a pattern, simply place the tape next to the row or section you want to mark. You can easily see through it to follow the pattern clearly. If you need to change the marked place, just peel off the tape gently and re - position it where you need it. As for maintenance, keep the tape in a dry place at normal room temperature. Avoid exposing it to extreme heat or cold, as this could affect its stickiness. Also, don't bend or crease the tape too much to keep it in good condition for your next project.
