On first glance, this trio of European landmarks looks like quick sketches on aged paper. But look again a little closer and you'll see that they are made from something much different. These ink-less sketches are actually made using thread on your regular sewing machine! Jessica from Running With Scissors used her creativity to sew these images into tea-dyed fabric. The secret is using a free-motion foot for your machine.
I admit that as a quilter, I'm fully aware of how this is done (not that I'm any good)... so for those of you who don't know, a free-motion foot allows you to move fabric in any and all directions by hovering just above the fabric instead of clamping the fabric between the foot above and the machine below. With that kind of freedom, you can sketch anything in thread!
