Well, first I don't have any set layout. I do each from scratch, since size and style vary. Put generally, I do these with Photoshop, using layers and feather cutting the edges of the area of the image I want.

I'm not sure what programs you have at your fingertips at the moment. I know you said that GIMP wasn't working well for you. Does that have layer capabilities? What other programs do you have available either at home or on campus? Once I know that I can email/message you some general directions. :)

btw, how are those drabbles coming? I'm just curious to know if you need anymore inspirational carrots. :D
