Here are three great options for booklets to use in the back of your planner: the Clairefontaine stapled notebook, the Rhodia stapled notebook, and the Quo Vadis planner booklet insert.
The Clairefontaine booklets are staple-bound and have 96 pages of 90 gsm paper. The Rhodia booklets are staple bound and have 96 pages of 80 gsm paper. The Quo Vadis Notes booklets are extra slim with 16 pages of 90 gsm paper.
These booklets fit in desk size planners, not pocket. The planners these booklets will fit into are the refillable-cover Scholar, Minister, Academic Minister, Hebdo, Space 24, Trinote, Septanote, Principal, Note 27, President and Prenote planners. (Planners sold separately.) Below you can see an example of how the Clairefontaine booklet fits into the back cover of a Scholar planner:
Will you use your booklet to make notes, to track your finances, or as a Bullet Journal? Will you convert it into a monthly calendar, use it to plan a trip, or decorate it as a creative outlet? The options are limitless, it’s all up to you!
