Used child sized boot (I have never been able to throw away my son’s adorable boots, so I have dozens sitting under my work table).
Gravel or small rocks (I used old fish tank gravel that we had sitting on our back porch).
Potting soil (or dirt from the ground)
Rockery plants (I plucked some hens and chicks from our rockery)
If boot has not cracked yet (unlikely since they seem to crack within 30 days of purchase) drill hole in bottom to release water.
Add gravel to bottom of boot, filling foot area.
Add potting soil to top of boot.
Gently insert plants.
Set outside in garden.
Enjoy whimsical garden art.
