DIY garden stones - use a cake pan! Also, using clear contact paper to hold the mosiac pieces in place while the concrete sets is also kind of brilliant. I want to use mirror pieces, red gems, and black cement dye.
Mixed paving materials - I like how this looks, plus it makes repurposing easier! CT - note: Could get some pavers that match front walk and combine with other materials to tie both looks together. Definitely want the walk to be permeable.
