Wow! What a great idea. I saw this cool stepping stone DIY online and had to share it with you. Oh...if only I had a garden (sigh). I'm also wondering what kind of leaf that is. It's HUGE! Sorry that this is an inspirational DIY post. I don't have specifics about the "how to" because it was all in Swedish. However, you can read more about doing simple concrete pours at eHow, or watch a video at HubPages.
