I am posting vintage sewing patterns to sell for someone else. I have 57 patterns waiting to be sorted thru, cataloged priced and posted. While I have sold on line before, never patterns. This is going to be a learning experience. We will be splitting the profits so I'm not doing this just to take up my time. Has anyone on this site done this before? I am not sure about how to categorize for best sales results . I am open to suggestions if you have any experience. Thanks.
