I LOVE creating unique composites!!
10 x 20 is ideal for 5-6 images. Can also include name
10 x 13 is designed for 2-4 images
10 x 30 can handle 8-10 images and is mounted on double thick mat board
8 x 10 is ideal for up to 5 images. There is typically one focus image in the middle with the others supporting it.
11 x 14 is similar but typically includes 5-7 images
5 x 30 is perfect for narrow locations. 5-7 images work well here. This is printed on double thick matboard
