I know a lady who was asked to leave a local store which features hand-made local crafts because she was looking at each item and telling her companion how she could make it (and she could- very talented!). She was indignant when the storekeeper asked her to leave because these crafts help support our local folks. I say good for the store owner. Basically, when you closely examine a crafted item and make comments to someone else how to make it, you are stealing!
