I think most are too small to mail on their own. you could always mail them in a small envelope.
This is the only reason, that I could think of that it would not be a good idea since they might get lost in the mail. Good idea about "upgrading" the envelope lol.
It isn't that they would get lost, the post office won't accept them because they are too small. You would need to put them in a bigger envelope.
Ok, I did not know the post office won't accept them. Thanks for the heads up. I may just buy the small cards and mail them in a regular envelope, or I may just go to the dollar store and buy some regular Valentine's Day cards and mail those.
H's nieces and nephews mailed us some last year. I don't remember exactly ho they came but we got 3 of them (from the same household) so I assumes they were in a larger envelope. That is what I would do because on there own they are too small.
This reminded me I have to do some ofr the kidlets day care. I suck at tshi. SHppid; I send a bag of cady with the valentimes. THat uskcs causde twins mean 2x cnady.
