Although babies can see the world in color, their vision is immature and they show a preference for high-contrast objects and bold patterns like stripes. Fabric company Michael Miller has developed a line of fabric called First Sight with these vision limitations in mind.
The line includes twenty fabrics - all combinations of black, white and red. And if you're looking for ideas of things to make, there are numerous tutorials on the Michael Miller blog, Making It Fun (created by Joanna of Stardust Shoes) including bibs, soft blocks, rings, car seat covers and more.
