I’ve always thought that I do a pretty fine job of folding t-shirts. They come out nice and uniform and without any wrinkles. But my folded shirts end up making a smaller rectangle and they’re an inch or two thick. With this MiracleFold device, my shirts fold up perfectly with no wrinkles and a nice uniform size. But most importantly, the shirts are very thin. A stack of folded shirts takes much less space than they did when I folded them my old way.

One small tip that worked well for me. Stretch the sleeves out to the sides far enough to create a little tension, and then hold onto the sleeve when you make the fold. That keeps the fabric taut and prevents wrinkles.
