The Design Brief® | Volume XII | How to Use Color to Alter the Perceived Size of Spaces

Of all the tools that interior designers have in their toolkits, none is as impactful and effective as color. Not only does color provide the mood and liveliness in spaces, it can also be used to alter our visual perception. Particular tints and shades of colors used in combination can create the perception of more (or less) space than actually exists, produce an increased sense of openness, highlight and draw attention to one wall over the others, or, conversely, create the sense of a more constricted, cozy, or comforting space.

This blog and this blog covered some basics of color theory. Here, we will take a look at how color can be used to alter the perceived size of a space.

Interior Designer Sales Tax Series Part 01 | Origin-Based Versus Destination-Based Sales Tax: Which One Applies to Your Business?

This sales tax blog series was written by Dakota Design Company and evaluated by CVW Accounting, 2/24/25.

Sales tax is a complex topic, and one that prompts many questions from interior design business owners. This post is part one of our Sales Tax Blog Series.

First, if you are purchasing to-the-trade-only products, and selling them to your clients, you already will have a sales tax permit (that allows you to make purchases without paying sales tax). You should understand how to invoice your clients for the appropriate amount of sales tax on transactions and how and when to remit the sales tax you collect to your state Department of Revenue for state and local sales tax. For any designer who needs a refresher on these sales tax basics, please read this post that covers all this need-to-know information.

If every project feels like a custom job and your workflow is all over the place, you’re making business way harder than it needs to be and I have a GUESS as to what’s happening.

Ready to stop reinventing the wheel with every new project? This is EXACTLY where I would start if we worked together 1:1.

Proposal vs. Contract: Should You Send Them Together or Separately?

When presenting your design fees to a potential interior design client, do you send the proposal first and the contract later? Or do you send everything at once so they have all the details before signing?

Some interior designers separate these steps. Some do them at the same time. Some send a contract out later, like mid project (🙀). Others don’t use a contract at all (🙈).

Obviously—the last two? NOT good strategies.

If you want a process that protects your business, builds trust, and keeps projects running smoothly, the proposal and contract go hand-in-hand.

PS: I’m not an attorney and this is not legal advice. This is based on my experience working 1:1 with over 100 interior design businesses.

Keep reading for my advice on when to send these two documents.
