Engagement Card

My sister is engaged! So to send my congrats, I made her the usual care package I always do every semester (possibly strange since I'm also in college, but I like doing it). However, this time I included things for her fiancé and added a congratulations card inside. With every card, I've been making it a habit to draw something; but I've never done an engagement card before. She is a marine biologist/chemist, and he's a scientist as well, so..... this goes to you, sis!
