Your Dryer, ftw :: 24/31
If you sell clothing, it is most likely going to end up wrinkly by the time you get around to selling it. A lot of time I will get things washed & folded and then it will be a while before I get to taking pictures and they are wrinkly all over again.
A couple years ago, when I was first selling, I told my sister how I had spent a long time ironing. She told me she just throws her clothes in the dryer to get the wrinkles out. WHAT??!! I tried it and do it all the time now. (thanks, Seester!)
On photo day I will pull all the items I want to take pictures of and throw them in the dryer with a damp hand towel for 20 or so minutes. Voila! No more wrinkles. (or at least very few!)
