All the quick responses from everyone are such a great valentine
present! Thank you all.

The good news is that NECCOs has GF conversation hearts.  And what's
also terrific is that the NECCO FAQ section has a question about which
of their products are GF: http://www.necco.com/
Frequently%20Asked%20Questions.htm#gluten%20content

It's such a gift when a company makes GF info so clear.

One person responding to my question said that Farleys and Starks also
have GF conversation hearts.

Happy Valentine's Day!
