I Did not see gummed envelopes at Home Depot which is where I got my last supply. I do not go to Walmart, it is way too far away.
I prepare 350+ Christmas cards for my dog rescue organization. This reminds me that I should probably warn the Christmas card buyer not to ever get sticky back envelopes in a misguided effort to “help me “. I will resign from that job!
When I am ready to close up these 350 cards I sit down with a damp rag and swipe the envelope tips and all is well.
