This is what I have been doing on weekends for the past couple of months, in the name of a more beautiful and dog-proof backyard, with really rather striking results, once the finished product is set on a layer of sand, and surrounded with pea-gravel.
Go to a craft supply store like Michaels’ or Hobby Lobby, or even the aisle at Walmart where they have the flower-arranging supplies. Buy a couple of bags of those flattened glass marbles, or the sea-shell shapes, ornamental polished pebbles, or the pieces of tumbled sea glass, or little square tiles, or whatever, in whatever colors work for you as a truly creative human being.
Go to Lowes’ or Home Depot, or whatever they call the home DIY outlet in your neck of civilization and buy:
A bunch of those heavy, clear plastic plant saucers… the 14” to 21” ones work best, but last weekend Blondie and my neighbor Judy from down the road seriously came down on me for wanting to buy a 30”+ one! I wanted to seriously create! Help, help, I’m being repressed! The best ones are about two inches deep, or have regular ridges along the sides, which allow you to easily set a level.
As many sacks of mortar mix as the back of your car, and your own back can handle. It comes in 40lb bags which tend to leak, somewhat.
A bag of those rubber gloves they sell in the paint aisle. Seriously, working with mortar mix is not something you want to do with your bare hands. If you don’t have a large bucket or some kind of cement-mixing trug at home, buy one of those, too. I have a large bucket which once held about 10 gallons of kitty litter, and a small GI-issue shovel, which works for me.
A couple of stiff plastic and/or wire brushes. They have inexpensive ones in the same general area where they sell paint-stripper.
Set out the plastic plant saucers on a level surface.
Mix the mortar mix with water— generally about one quarter to a third of water, to the amount of mortar mix. It should be just damp and slushy enough to stick together. (Do not use too much water. It will not work well, trust me on this.) Stir well with whatever you have, and only handle the stuff with gloves on.
Slop enough gloppy mortar-mix into each plant saucer, and slap with your hands to pack into place. Don’t worry, if it seems too dry, at first. The water will rise to the surface, and saturate the whole mass of stuff in the mold.
When the mortar mix is packed into mold (one forty pound sack fills one large, two medium and a couple of small saucers, although your mileage may vary) level it off, and set the marbles, glass, pebbles or glass onto the surface. Slap it gently to embed them in the mortar. Be creative, this is when you let your inner artiste have free rein. Don’t worry if some of the mortar slops over the glass a little bit.
Allow to sit for at least 6 hours. If you haven’t added too much water to the mix, it will be solid enough to un-mould. Let them sit for another six hours, or overnight, and brush the dried surface with the wire or plastic brushes, to clean off the glass inserts, and make a nice roughened surface of the mortar.
These will look really cool. You can also lay flat leaves onto the wet mortar, and press them in just enough to make leaf-printed stepping stones.
Note: I have used purple and green marbles, and real grape leaves to make a lot of stones with bunches of grapes set in them. But remember to wear plastic gloves, this stuff is hell on your hands, otherwise.
