sew: sewing, random craft projects, cooking (that doesn’t really fit, does it?)
math: I’m a mechanical engineering student, so math is an integral part of my school life, no pun intended.   This explains any nerdy posts.
vintage: I worked at an antique mall in high school and developed a general love of all things old/retro/vintage/antique.  I currently have an overwhelming obsession with vintage Pyrex.
Oh and I’ve always liked the colors of lichen.
