Cut some shapes to make stencils
If you have some leftover paint, do not throw it away; get a plastic sheet in which you’ll cut different shapes, with great care obviously, and give a new look to your pots. Stencil is one of the most accessible techniques one can do.
Just support the sheet with the shapes on the pot, remove it very slowly and see the result. You can try different shapes on paper and then see which ones you like the most. Easy, right? Cut more shapes and decorate the pots with the most varied motifs.
