To get you ready to hit the ground running on our 30 Days of Cardboard Crafts, here is some inspiration for Day 1s Challenge: Make A Start Sign.
Even though the sign says love, you get the picture. The letters are made completely out of cardboard and you could do something similar with your child! Its very easy to make and they look adorable!
Make Signs Out of Cardboard
These letters are placed on a cardboard background with a cardboard border that can be colored with crayons and markers, or painted.
DIY Lighted-Letters Sign
If you feel optimistic and want to get really fancy with your letters, you can always add some lights to your camera and action. These well lit letters are made completely from cardboard and (surprisingly) looks pretty easy to make.
