I ordered an etoupe canvas strap in a super short length and another etoupe canvas strap in a longer cross body length last week and the estimate came to $650 USD before taxes. I didn't have to leave my bag. They just made note of the bag's leather type, clemence, for the leather ends of the canvas straps. The materials are coming from Paris but the straps will be made by a San Fran craftsman (Dominique) for faster delivery, I'll let you know how much I actually get charged when the straps come in! HTH'
