  1. Good job Jennily! I like how your post was very colorful, although you shouldn't have colored each question a different color, and instead pick bold and dark colors. Also, remember to put a video and link. I really like your pictures too. For each question you should have explained on more what you did to get the answer, especially for number 11. I like how you took the time to do the scribe on your birthday. Speaking of birthday, HAPPY BIRTHDAY!(: Hope you have a great one.
