I used four different types of wrapping paper that I got from the dollar store. I started with measuring the box with the paper and cutting out each area to fit.
I placed each piece in the box to make sure they fit and creased the paper along the edges so when I went to glue them in they wouldn't be giving me any trouble.
After all the pieces were cut and fit correctly I started applying the Mod Podge along the inside of the box doing one section at a time.
Then get the creases out and help the paper stick.
And viola! One birthday care package to go.
