Hope all this info helps! To each her own though. You have to do what works best for you and your space...
Here is my circle time display boards. As you can see I prefer to use my wall space for toys and shelves. For years, I had my circle time materials on a bulletin board, but it bothered me A LOT that the children were not able to interact with the materials. So I decided to attach everything to black tri-fold display boards. I laminated EVERYTHING and then attached it all with Velcro. They are hung with 3M hooks, so we take them down daily. The kids LOVE it when I take them down, and they know that the best cleaners get to be my circle time helper. :) When I take them down, I just lean them up against the table. The materials have held up well all year. I use my home Lakeshore Laminator to laminate everything. The 5ml laminate sheets are practically as thick as a credit card!!!! It is well worth the investment!

This is our first board. We sing the days of the week and months of the year song daily, so I wanted all the months posted. The kids know how to figure out which month it currently is because they can sing our circle time song, and see which month is missing and posted above the calendar. I chose a separate weather display, because I wanted one that taught the seasons. I also focus daily on the weather versus how the weather feels (those are two different things in my eyes.) You can see the black Velcro blends in to the black display board. I like using black the best, because it makes the colors pop, and it gives the look of a school blackboard.
This is our second board. We sing our ABC's daily and follow with a chant of all the letter sounds. We review our letters, sight words, numbers, color, and friendship words daily. I point to our thematic poster and remind the kids what we are learning about. All of this is part of our morning routine. The kids truly love it! I catch them singing our circle time songs throughout the day. It sounds repetitious, but it provides a sense of stability for the kids. They know what to expect each morning before we begin our topic for the day.
I also created this "Bubble Gum" word set. I purchased this on TPT. We only do this a couple times each week, but the kids look forward to it. They practice spelling and reading a CVC word. I give them a random CVC word to spell (first board). Then another volunteer chooses a bubble gum word from the basket hung on the wall. They practice reading it and sort it in our pocket chart. They always giggle a lot when they get a silly word.
This is our map of the world. This is also hung on hooks, so it comes down when we need it to. I attach the monthly flag with Velcro, so I can switch it each month.
You can see I had to clip my 3M hooks a bit, so the display board could come on and off easily. It has held up perfectly all year though.
