K...so the shipping costs have been making me crazy. I hate that it costs so much! I usually end up eating a portion of the cost myself, with the cost of the mailing tube I was using and the crazy price of shipping it. So I've really been brainstorming ways of turning my small package cost into an envelope cost. I think I've found the answer.
I purchased a size three bubble envelope and have cut it in half, providing two mailers at the exact size I need! 4 x 14. So excited about this and the potential for waaayyy cheaper mailing this will provide for my customers. Gonna send out a few sample mailings before I confirm a cost.
