One great way to get paid a commission without appearing to sell anything is add affiliate links within your content. That way, when people click on the link, they're taken to the company site and, if they buy, you'll earn a commission.
For example, if you're writing about decor that includes purple comforters, make the phrase "purple comforters" a link to Amazon's site that shows people only comforters that are offered in purple. Your readers can browse through Amazon's offerings and maybe purchase an item that they like. Good news: Companies make it very easy to get links to their site. The way that you get those links varies from company to company, but it's usually very easy to find a link to the product or products that you're looking for.
