Thanks to everyone for your comments and a big thanks to Heather for posting yesterday and sharing her darling ideas. Expect to hear more from her in the future!
Now for the lucky winners.
Amy V. said: "Cool beans. Would love one of these number sets."
Sophia said: "I love the mailbox idea. I sure would love to win."
If you two ladies would send me your choice of number set and address to firstname.lastname@example.org with Blog Winner in the subject title, I'll get those right out to you.
P.S. If you want to make the world a better place, take a look at yourself and make that change. :)
