These posters and prints are easy to use. Just find a nice spot on your wall, measure it, and hang them up with nails or adhesive strips. Make sure the surface is clean and flat before hanging. To keep them in good condition, avoid direct sunlight as it may fade the colors over time. You can gently dust them with a soft cloth every now and then. Also, be careful not to get them wet or dirty. If there are any stains, you can try using a mild, non - abrasive cleaner on a small, hidden area first to see if it works.
