So, I decided to change pictures in my shop.
First thing I had to do is make a light box. it took me 10 minutes and costed 1.37 USD (tissue paper).
So I took a box from noodles, cut out 3 sides, leaving one inch on each side of each "wall". Then I taped tissue paper to each wall. Et voilà!
I bought lights at IKEA, but I don't think they are enough, I need to buy at least one more light and more powerful bulbs to avoid yellow shades.
Here are some pictures that I took today
