Many artists see their studios as a science lab with experiments bubbling away in every corner. Like scientists, some experiments yield something interesting and worth investigating further, others do not. In my practice, I do many experiments with materials and ideas that may or may not ever turn into something useful.
Here is something I've been experimenting with. It's a fabric mold for concrete.
Here's the sketch idea.
Here I am sewing the fabric mold.
Here the mold has been filled and is held in place by inserting a stiff upright into the center and stuffing plastic around the inside.
And finally, here is the final (not super successful) product. This is one of those experiments that warrants some more attempts. I am currently waiting on a new fabric mold to cure.
