dltk-kids.com and just tweaked it for my purposes. This card is simple, requires minimal grown up work, and gets your kids creative juices flowing.
First I altered the printable from the website to the size that would work best for Smarties or a snack size candy bar. I also put four cards per page so there was less printing. Here is my template.
Next cut out the cards by quartering the page with a cutting board or scissors. Now let your kids get creative & color in the picture. Then have them write who it's to & from on the back (or the front if they can write small enough).
Lastly I just used a glue stick to attach the candy & they were done. Super cute homemade cards are the best. You can easily alter this project based on the child's age & skill level. Happy card making!
