Sivason's post is almost exactly how you're supposed to do it. His post just needs the target codes next to the target, and that's it. His drawings are simple, which is completely fine. Everyone should be able to draw some lines on a paper, and write a word list for each target. Just a word list, not a sentence describing it.
Also, I forgot to add that you should use one sheet of paper for each target. This helps us from getting impressions jumbled. Also, remember to write the target code at the top of the paper. There are less than 24 hours remaining before I reveal photos of the target objects for the week 1 experiment. I am looking forward to seeing the results of this experiment.
