Cardboard picture/photo frame DIY

First you need a good pattern. I watched a lot of frames images before I developed my own. 

I have two frames of different width glued together, I covered them with thin paper and wooden glue which I dissolved with water by half&half.

 After it is dry I spray painted it with white and put on the wall on double-sided tape. I did not need the back side of frame because I already had adhesive chalkboard on the wall.

Good luck!
