Anyone know of a store that sells pretty seals to go on the back of envelopes in the Galleria area? My invitations are awesome but the lining is a bit thick so when you moisten, you have to press the seal down for 10 seconds+. I'd feel more comfortable if I had a seal on the back as well. I'd like to get them all addressed and out by Monday so if anyone knows of a store where I can pick up seals today, I'd be grateful for the recommendation.
