How to close a gap

1. Find the gap. Zoom in (pinch or scroll) where the paint leaked. Look for a line with a tiny break.
2. Tap both ends. Choose Close a gap, tap one end of the break, then the other. The line snaps onto the drawing.
3. Paint again. The area is closed now. Your lines are saved on this device only and are included in your download.
