I recently ordered 4 Mondo Bag kits for some friends and myself. We then decided that we really only needed one with a pattern and could just get the interfacing for the remaining bags, I emailed Melinda and she was gracious in saying I could return 3 of the kits and then just get the interfacing needed for the remainder. In the end we kept the four initial kits and ordered 8 of the interfacing only. I was very impressed with Melinda being so accommodating and also how quickly I received the shipments. Each time I ordered I received my order in 2 days. What great service. Thank you!!
