It looks so cute and calming! It's refreshing to see a room makeover that doesn't involve buying a bunch of new stuff. Love how you swapped dressers with your sister instead of buying something new
I stick mine up with either blu tack or scotch tape. Tape you have to be really careful with depending on the type of paint on your walls. For lighter posters and pictures, masking tape or washi tape works well. 😄❤
