About wrinkles: The photography background is shipped folded for easy transportation, but this does not affect its use. You can gently iron it from the back or roll it into a cylinder for 3-4 days to remove wrinkles. About size: This backdrop is ideal for children's photography, but we also offer custom size options. Please note: The main image is to show the effect, the back supports are not included. There may be a slight color difference due to the settings of each computer screen.
