Each note does include some cute doodles on them so maybe if you can't draw, or your kid thinks that printed stuff is better than your handwriting, these might work for you.
You can find the notes at: www.lovablelunchnotes.com. They'll be releasing new ones each week over a six-week span starting this week.
In case you're looking to save some money, there's also a coupon for 35 cents off any 20-oz variety of Sara Lee on the site as well.
