I did not follow this tutorial completely. I only have two lights so I did not cut the window for the top. Mine is also larger and I made the bottom different. This is my first light tent made from foam board and I enjoyed working with it over flimsy card board. If you have an online shop and can not take your photos in natural light, a light tent is the only way to go! Trust me, photos always come out better this way :D The picture with the candy corn was taken with this light tent.
