Use vinyl paper to give them a marbled look
Marble always makes counters and tables look tasteful and refined, but it requires quite a significant investment. So, marble-patterned vinyl paper is a great way to get a fancy appearance without paying too much. After you finish wrapping your kitchen, you can use any scraps to make some DIY coasters.
You only need to cut some balsa wood into squares and wrap it with vinyl paper in the pattern of your choice. Leave a section of timber uncovered to give it some contrast. You can also add some gold accents with a golden permanent marker to make them look extra glamorous.
