There are so many options for purchasing journals from very inexpensive notebooks to elaborately designed field books, and your choice will mostly depend on your preferences as to where and how you will be doing your nature journaling. Some students prefer journals with blank pages, others like the dotted and lined pages. Some students like to collect flowers and leaves, so a field folder would be appropriate. The important element is to have a place to keep your journal responses all together as a record of your thinking and for reflection purposes.
