Today I took 15 minutes to make a light box to snap pics of my yarn. My current method does not filter the light, it is direct light, let's take a look at a before and after...
Before and after:
Huh, quite a bit better in my opinion.
I modeled my box after the this one.
I grabbed the best box I could find, which happened to be a 12 pk corona box, not very big, but it's all I had to work with. I cut out the top and sides, just leaving a long strip for all four corners. I then taped some white computer paper the the outside of the top and sides, laid a sheet on the back and bent it into the bottom and that's it. It's totally not sturdy, but it'll do until I get a better box and some poster board.
