Lassoing And Moving An Image

To lasso a part of the image you are working with, firstly select the lasso tool from the toolbar on the left hand side of the screen like so:

Once you have selected an image using the lasso tool you can then move it to where you would like it to be by using the move tool on the left-hand tool bar. By creating a duplicate background copy before doing so you can double the area you are selecting.
