Here is the how-to for the smallest of these super nifty garden mushrooms! You can of course take this how-to and tweak it, this is a pretty forgiving project. The measurements I've given are just a guideline and you can use whatever size pots, and saucers you want, given of course that they fit together. Since the The how-to for these mushrooms is pretty long the directions for the two larger mushrooms are posted on my blog.
To make the base, or the stem of the mushroom take the smaller of the two terra cotta pots (make sure it's clean first!) and using the ceramic tile adhesive, glue it onto the larger pot (just like you were stacking them together ). Let dry for 24 hours.
After the stem pots dry for 24hrs, paint the mushroom stem with acrylic paint. I used a tan base coat, let that dry then applied a lighter creme or tan color. Using a dry sponge I dragged the lighter shade down the sides for a layered effect, it makes it look more like a real mushroom stem. Let paint dry.
After paint is fully dry, affix the terra cotta saucer, for the mushroom cap, to the base pots with a liberal amount of ceramic tile adhesive, let dry for 24hrs again.
Now using the tile adhesive again begin applying the flat marbles and pebbles on to the top of the mushroom cap, and down the sides, in whatever pattern or colors you wish. You can substitute more flat marbles for the pebbles if you want to. When you begin affixing the marbles and pebbles to the sides of the mushroom cap, they might slide a little, so sometimes you have to hold each marble or pebble in place for a few seconds until it sticks by itself. Let dry for 24 hrs again.
(This image is actually the cap of one of the larger mushrooms, I apologize, but I didn't have any pictures of the top of the small mushroom).
Using grout on the mushroom's cap is optional, I chose not to, but if you like that look go for it! If you are putting your mushroom outside make sure to spray it using a water resistant clear gloss, or matte spray coat.
Congratulations! You are now the proud parent of a beautiful baby garden mushroom :)
