For most any envelope, I'm willing to make a matching power pouch (providing I have enough fabric, of course) for $12. Convo me if you want one!!
Please be very careful about size when ordering envelopes. I want you to be happy with the fit! I am constantly making new envelopes with new fabric. Part of my mission is to make well constructed, unique products -- not the same thing in the same fabric over and over and over. That way you have something that's truly special!
