A little imagination, a cement-sand mixture and 48 hours - that's all it takes to create cheap and beautiful things.
First you need to prepare a large container for mixing the solution. You will need cement (1 part), fine sand (3 parts) and water. Mix the sand and cement first. Add water in small portions. The solution should turn out to be liquidish, somewhat reminiscent of thick sour cream in consistency.
Then saturate the fabric in the mixture (large terry towels will do). A thin cloth will absorb little solution. Thin fabrics will make products that are too fragile, so it is preferable to use terry cloth.
Then hang the soaked cloth on a pot or bucket covered with foil.
Let dry completely. This will take about 48 hours.
After drying, you will get an original planter.
