If you are talking about a template...then I can help you. LOL
It took me forever to figure out how to use them. If I have a black line that I want to put my paper in, I simply drag the paper over so that is on top on black line then I do
Layer>group with previous
Now remember it is going to attach itself to the previous element so you have to make sur eyou place it in the right spot.
When I do it this way I add the drop shadow to the black line layer and then my paper will have the drop shadow since it is attached.
Am I making one bit of sense?
