First of all, you should make sure that your glass vase is dry, clean and free of grease residue. Mask the vase with adhesive tape in the areas where you don't want any paint to get on. In our case, we opted for different sized strips of paint. Once you have chosen a color of Edding permanent spray, turn the vase upside down and spray evenly and in light coats in a criss-cross pattern to achieve an even result.
Allow the paint to dry briefly and carefully remove the adhesive tape . Then allow to dry thoroughly, we recommend 24 hours.
