If you find you’ve drawn something in the wrong layer, or you’d like to reorganize parts of your sketch to other layers, you can select and drag items between layers easily.
1. Tap the Layers menu to open it.
2. Use the Selection tool (Lasso or Item Picker) to select the items you’d like to move.
3. Drag your selection to the layer you’d like your strokes to be in, and let go. Your strokes will return to their original position on the canvas, but they will be in the new layer.
4. To create a new layer for your strokes, select what you’d like to move, tap “+ New Layer” or drag them to the “+ New Layer” button, and let go. Your strokes will return to their original position, but you’ll see a new layer appear with your strokes in it, immediately above the current active layer.
