Quick Answer

If you plan in a Hobonichi Weeks, buy a Weeks kit such as the Roadtrip Hobonichi Weeks Kit. If you plan in a Hobonichi Cousin, buy a Cousin kit like the Thanksgiving Theme Hobonichi Cousin Weekly Kit for weekly spreads or the Summer Mermaids Hobonichi Cousin Monthly Kit for monthly spreads. Match the kit to your planner model and the spread you decorate most, not to the theme you like best.

What Actually Differs Between a Weeks Kit and a Cousin Kit

The core difference is the planner the kit is cut for. A Hobonichi Weeks kit is designed to decorate a weekly spread in a Hobonichi Weeks planner, while Cousin kits target the larger Cousin page. The Roadtrip Hobonichi Weeks Kit is built for one weekly spread in a Weeks planner. The Thanksgiving Theme Hobonichi Cousin Weekly Kit is built for a week in the Cousin, and the Summer Mermaids Hobonichi Cousin Monthly Kit is built for a month in the Cousin.

Sheet count is the second difference. The Thanksgiving Cousin weekly kit is a set of 3, and the Summer Mermaids Cousin monthly kit is a set of 2. The Roadtrip Weeks kit is sold as a single kit. More sheets means more stickers to place, which suits a fuller weekly or monthly spread; a single kit suits someone who decorates one spread at a time.

All four kits share the same material and sheet size: printed on writable vinyl, 4.33 x 7 inches, and resistant to smudging from gel or ballpoint pens. Because the vinyl is writable, you can add notes directly on the stickers instead of leaving them blank.

How to Match the Kit to Your Planner

Check the model name printed on your planner cover before buying. A Cousin kit will not fit a Weeks layout, and a Weeks kit will not cover a Cousin spread. If you own both planners, buy one kit for each rather than trying to stretch a single kit across both.

Then decide which spread you decorate most. Weekly planners get more value from a weekly kit; monthly planners get more value from a monthly kit. If you decorate both, a weekly kit and a monthly kit from the same planner line cover the two rhythms without overlap.

What the Spooky Kitties Mini Kit Changes

The Spooky Kitties Mini Planner Kit is a different category of product. Its stickers are 1.5 inches wide and fit most planner layouts, and it comes with 2 matte paper sticker sheets. It is not cut for a specific Hobonichi spread the way the Weeks and Cousin kits are, so treat it as a flexible add-on rather than a replacement for a model-specific kit. The catalog does not list a full sheet size for this kit, so check the listing if exact dimensions matter to your layout.

Trade-Offs at a Glance

  • Cousin weekly kit (set of 3): More sheets and larger page coverage than a Weeks kit, but it only fits a Cousin. Buy it if your weekly spread is the main page you decorate. Best value when you fill a weekly Cousin spread every week.
  • Cousin monthly kit (set of 2): Fewer sheets than the weekly set and aimed at monthly spreads. It will not cover a full weekly spread without supplementing it. Choose this if your monthly page drives your planning.
  • Weeks kit (single kit): Cut for one weekly spread in a Weeks planner. It will not fit a Cousin page, so it is wasted if you plan in a Cousin. Buy only if you actually plan in a Hobonichi Weeks.
  • Mini planner kit: 1.5 inch stickers fit most layouts and it includes 2 matte paper sticker sheets, but it is not model-specific. It works alongside a Weeks or Cousin kit rather than replacing one. Use it as a gap-filler, not your primary kit.
