Long ago I wanted to customize a table from Ikea that I have at home which is not very graceful and I came up to decorate it with some decorative vinyls.
You can buy these kinds of things in many places, but if you can’t find a design that suits what you want you can make them yourself using adhesive film of the color you prefer.
Draw your design on the back of the adhesive paper and cut it out.
Take off the paper behind the film and place it carefully on the surface you want to decorate. I wanted to draw some flags that is very easy, but you can make any design you like.
