Review: Cutest little easy to use planner - Well first of all, this is so cute! Absolutely love the holographic lettering. This planner is perfect if you’re inconsistent with your planner like me since you have to write in the months 😂 lots of space in the squares and nice and thin/easy to pack along with you. The book itself is fairly thin so be aware of that— it’s not going to be super durable if you’re throwing it in a bag or against any sort of accidental liquid encounters. But besides that the quality is great.
Review: My favorite planner - I love having a planning to stay organized, especially with all the events and meetings I have to attend. I finally found a planner with a layout that is exactly what I want. I have never been a fan of planners that include all the extra weekly and note pages. I just wanted the month to month part. This is it. Plus I’m able to decorate each month to my own liking. The size is also perfect. I needed something that is big enough to write out everything all my dates but small enough to travel with me every day. The pages are thick so there’s no bleeding through. I have used a variety of pens and markers. As soon as this one is full, I’m buying another.

### ⭐⭐⭐⭐⭐ Absolutely perfect - if this is what you need ;)
*by M***E on August 11, 2024*

I started using this in January of 2024. I realized, today, just how amazing this thing is. First off, it is well made - nice, thick paper that stands up to being carried around in my backpack, using pencil, pen, and sometimes highlighter. I love that it starts on Mondays. My daughter thinks I'm a weirdo for preferring a Monday start but I like it because I always worked a M-F type job and don't like my weekend being split between weeks. I like the fact that I can start any month I want! Coincidence, I needed to start in January but nice flexibility. I love that it goes for 17 months. I sometimes have delays in getting the new year so I have some wiggle room. Also, if you schedule things in advance, you have an actual calendar for those extra five months. I also use the blank page after the 17 months to note other items that get scheduled even further into the future. I love the extra column for each week. When necessary I can use it for those weird things that have a time frame but not an exact date. I also use it to write addresses of appointments. Because you write your own dates in, you can choose how to deal with "six-week" months. Those are rare, so a default of five weeks makes it perfect but I have a preferred way to handle them and this works (I don't like sharing a square for two dates because then you have to write so small that you can't read what you wrote). I added two items but not dropping a star, just because they weren't included. I added an elastic band (found via travelers journal accessories) to easily flip to the current month. I also added a 'corner pocket" so that I can slide those slips of paper into the back cover without them falling out all the time. If you need those items, easy to add them and the total is still cheaper than many calendars - that don't work as well!
