Accurately measure the wall space. Keep your pieces 2-3 inches apart and the spacing consistent between each piece. Take a step back from time to time to help you maintain a sense of perspective.
Framing
This is the part that brings the artwork to life. In order to ensure longevity for your pieces, they need to be framed. I have all frame sizes available to purchase in my shop.
Decide on the order and angles before you start hanging. Keep in mind the lighting in the room, as this can elevate the artwork. I would recommend using command strips if you do not want to damage your wall paint.
