These are the tools you'll need to make a soft box. A box, tracing papers, blade or scissors, glue and a pen.
Mark and draw lines on 3 sides on the box to be cut.
After cutting, it should look something like this.
Measure and cut 3 pieces tracing paper according to the parts you have cut on your box.
Now stick the tracing paper on the inside of the box. This acts as the light filter.
Cut two more pieces of tracing paper for the remaining two sides that were not cut out & stick them onto the cardboard surface so as to not reveal any cardboard surface.
Now, place your prop for display in the box,shine the three torch lights through each side of the light filters and you'll have your very own home made soft box!
