Some cook, I sew and write: creativity brings joy

Here's my latest quilt, created to practice free motion quilting.  I think I used a little bit of everything I've learned so far because some of the spaces are irregular and some because I got bored with what I had already done.  I tried to do each type of element differently from each other too. Some examples (if you look really close!) The back side: Any chemistry teachers out there?  Homeschoolers?
