Step 1: Stick two tapes on the nail cover, leaving a gap between them. Note that the gap width of each fingernail is similar.
Step 2: joint filling. Use a small brush to pick up the golden nail polish and apply it to the space reserved by the tape just now.
Step 3: Do the same thing for each fingernail, and then remove the tape.
Step 4: Trim the edge of the gold thread with a toothpick or a pointed object.
