You can ask for a llist of all items that need to be made. Then go through them and say which arent able to be made in your shop. i.e the Victorian posy. This is the most common one, or silk items. Then the college/training provider can arrange for them to be made there instead. Obviously as much as possible is to be made in the workplace but sometimes this isnt feasible.
I dont recall my shops being unprofitable making things correctly. We had a reputation for quality.
