companies have jumped in.
I used a sheet of kraft corrugated from Creative Imaginations as a background.
Don't worry about it bulking up your albums as it's not very thick.
I used Jillibean letters and made my trees out of cardboard for a homespun feel on this Christmas layout
Another way to use corrugated letter sheets is by cutting out the negatives like this layout where I used it to show the number 7, how old my son is.
To achieve the corrugated look you can also use a paper crimper as I did on the circles of this layout.
