Sometimes I do my little doodles in my Bullet Journal. And sometimes I do them on little pieces of cardstock--especially if I want to use Sharpies or Prismacolor Markers. Because, though I ADORE them, they bleed through the pages of my journal. I put all of the drawings in a drawer of the buffet that sits next to the table where I draw. Not sure what I'll do with them all but opening that drawer and seeing them all there always makes me happy.
