I'm a fellow user and can't tell you what code to use. That's why I asked if that one would do.
From your description it sounds like you custom manufacture and install drapes "from purchased materials" as is also mentioned in the description, but perhaps on a very small scale. It said for " individual retail customers." It didn't say "retailers." I assumed a client would be a retail customer, unless you are selling to the customer wholesale. I admit it's confusing. Only you will know what all you do. You're free to search the NAICS codes at the link I provided, but you may not be able to narrow it down to anything that is an exact fit. I also tried to search on terms like "sewing" and some other terms without success. But have a go at it at the link above, and you may be able to think of some keywords to try.
