I know this doesn't refer to clay or ceramics, just wasn't sure where to post. I am looking for clear plastic molds to make stepping stones. I have a heart, butterfly and octagon shape from A.C.Moore, but would like other shapes or images. Online or in stores, any suggestions. I love making these for family and friends. Problem is, they have turned out so well that no one puts them in the dirt as it's intended purpose, they just prop them up in the garden.The heart has been my biggest success, I make them for weddings, anniversaries and Valentine's Day. I am partial to the butterfly myself.
