Matula works very closely with you to customize your canvas. One canvas can contain anywhere from 3-25 pieces of your child or children’s art. Once the designs and color selections are finalized, the art is processed and properly preserved. For a personalized collage like this, I would wait a few weeks; Matula can complete a project in 3-7 days! A 2’x4’ canvas costs $500 and a 3’x4’ canvas costs $550; however, to a mom or dad they are priceless. For more information email Matula.
