Our invites are an odd size (long story, don't ask). The envelopes that fit exactly are sold only by cases of 100. We have about 10 invitations to send out to my co-workers and 2 of FI friend's. I went and purchased brown kraft envelopes that are a tad bit larger. I am now having second thoughts on send invitations in brown kraft envelopes. On the flip side, if I order another case of the original envelopes, they are $83. FI says stick with the kraft envelopes and be done with it or hand deliver them to my co-workers. We are truly on a tight budget at this point but I am torn. What would you do?
