Zip file with the snow angel boy and girl.

Download and unzip the images.
Open the one you want to use.
Using the selection tool, trace around her arm
and down her arm pit. CLick on the arm to make it 'float'
add a layer under the arm and de-float.
Do the other arm the same way.
Fill in the white snow area with white.

duplicate the background and two arms 
to a total of four each. Position the arms differently 
and merge visible a body and two arms.
as the only part you are changing is inside the main image,
you can copy and paste each image as a new image.
see below.
I just thought of it, but it would be cute with 
and arm going the opposite way too.
