Amanda McCavour creates incredible images with thread. She describes how she does it on her website:
In my work, I use a sewing machine to create thread drawings and installations by sewing into a fabric that dissolves in water. This fabric makes it possible for me to build up the thread by sewing repeatedly into my drawn images so that when the fabric is dissolved, the image can hold together without a base. These thread images appear as though they would be easily unraveled and seemingly on the verge of falling apart, despite the works actual raveled strength.
