Concrete planters are very actual for modern décor because they are cool, simple and minimalist. We’ve already made some, and here’s one more stylish idea. Prepare a carton, 2 parts of quick-drying cement, 1 part water, a bowl, a spoon, masking tape, spray paint, scissors, a toilet paper roll and pebbles. Open and clean the carton thoroughly; mix the concrete in the bowl according to the instruction and then pour it into the carton. To make a hole, put the toilet paper roll inside and let dry. Cut and put away the carton, apply the masking tape and spray paint as you like. Plant cacti or succulents and enjoy!
