DIY garden stones - use a cake pan (from the thrift store)! Also, using clear contact paper to hold the mosaic pieces in place while the concrete sets is kind of brilliant. There is also a link to easy stepping stones using flagstone and grout
"How to make a pebble mosaic," Excellent step-by-step instructions from "This Old House." I just need to sort our stones, get more stones, and layout the design. This would be a good project to start in September.
Make Cement Leaves! In a bucket or pail, mix two cups of cement with 1 cup of water to create a thick paste. spread the cement mixture onto each leaf. Allow the cement to dry then Flip the mold over, and remove each leaf.
