Welcome to SolidWorks forums Amanda.
You would need to use 3d sketch over there from going between different planes while sketching continuously. I'm not in front of SolidWorks right now but making an animation would be cool. You can make 2d sketches at different planes with open ends and keep them hidden. Now using different 3d sketches simply connect their ends. Finally start showing the sketches one by one along with each 3d sketch and take your pictures for the manual.

Great- thank you so much. Thank you also for the forum etiquette post. I will look into both of these and see what I can do- much appreciated!
