Forgot to buy the Christmas wrapping paper and it's Christmas eve? Here's an idea:
Use junk mail!
It's colourful, it's free and at this time of year, you'll likely have piles of it stacked around the house (I know I do).
Add some ribbons (if you want to) and your Christmas wrapping is done.
The kids won't be concerned about how the presents look (they only care about what's inside), and if anyone has something to say, you can brag about how you saved $5 on wrapping paper while also up-cycling the junk mail. Go you!
