If you’re a knitter and you’ve been knitting from patterns for any length of time, you will have run across the advice to knit a test swatch using the yarn and needles intended for your particular project. I cringe at the thought of making test swatches because they feel like a waste of time. Let me get to work on the actual thing I want to make, please!
Usually I bypass the swatch and jump right into the project. When I’m finished, I am often annoyed to find that my piece is not the size I hoped it would be. Usually, it is too big. That’s the value of a test swatch in knitting. If I would do them, I would know whether I needed to adjust my needles in order to get the proper gauge.
Now that Erik has been seriously refinishing furniture for the past 5+ years, he has come around to learning the value of test swatches in refinishing.
As I’ve watched his process evolve, I’m amazed at how many variables there are to consider in refinishing a piece of mid-century modern furniture. Here are some of the variables he has to contend with:
- Type of wood – Some woods, like walnut, take stain evenly; others, like birch, don’t and will turn out blotchy if not dealt with properly.
- The stain – Color is a big part of this, but so are the composition (gel vs. dye vs. pigmented vs. wiping & etc.) and brand of stain.
- How finely a piece is sanded – If coarse-grit sandpaper is used before staining, more pigment will lodge into the wood and the stain will appear darker.
- The various protective coats – There are usually several layers of protective coats on a given piece. These can include shellac, de-waxed shellac, lacquer, polyurethane (known as “Poly” in the business), vinyl sealer, conversion varnish, and curing oils. The lacquer can be nitrocellulose, pre-catalyzed lacquer, post-catalyzed lacquer, or water-based.
- The condition a piece is in – If an old piece of furniture has been impregnated with a silicone furniture polish over time, this will contaminate a new finish if it is not properly sealed in. If it has been water-damaged, this damage has to be treated so that a shadow of it doesn’t reappear after the piece has been refinished. If a piece has faded due to sun damage, this will also affect the final outcome.
As you can see, refinishing a piece of furniture is not a simple matter of slapping on a new finish coat.

Because of all these variables (and more!) and the time it takes Erik to strip and sand a piece to bare wood, he has become a fan of test swatches. This is especially true when he’s trying a new finishing technique. He doesn’t want to get to the end of a project and find he doesn’t like the result. That would mean restripping the entire piece over again.
To create a test swatch, he finds a scrap piece of wood that is the same or similar to the furniture he is working on and tries a few finishing techniques on it, marking each trial with the variables so he can remember how to recreate the finish he prefers on the furniture.

Nice, eh?
