@Meg why not use an assembly item if you are indeed building ? Would it not work say make the chair as a component..it will always default when you create the WO(work order). Take note if the WO is not processed yet you can add or remove components to it which means you can maintain the same Assembly item but can reconfigure the BOM/Components everytime you create work order ..you can create non-inventory components to represent additional costs like spraying..drying...packing etc- This is if you build it in house. If there is a third party supplier like a contract manufacturer, try using the Outsource Mfg feature. I tried it in one implementation..probably worth checking
