How to construct a DM screen

I use a screen i bought for now.
Honestly, I'm sure there's DIY all over the internet for different ways to make them. Hopefully you find a cool option and come show it off!

Personally, I’d say go to your local hardware store and buy some thin square plywood boards and some simple hinges. You can link the boards together and add clips for papers on the inside face. 
I’m not sure you will be able to make it fold up well if you have limited craft ability but it should work in the interim while you wait to buy or learn how to do a better one.

Oh yeah, our house rules are a hodge-podge of rules and definitely not 5e.  So I can't buy anything pre-made.  

 They actually make several DM screens that let you insert pages into them.

I just use a computer

So, what I did was I duct taped two half inch binders together so that they unfold as four attached panels with three fold lines, If you aren't clear what I mean, I can upload a photo later.

I also have my laptop with me, but sometimes I need a physical book and I need to roll dice anyways because Google Dice Roller just isn't as fun. Also, having to switch between a bunch of tabs on my computer is annoying and the DM screen creates a psychological barrier and if I just have my laptop out, people will think it's okay for them to be on devices.
