A stain colour on a shop display is only a starting point. Your species, sanding and topcoat will all influence the result. A useful sample records the complete process so the finish on the project can follow it.
Use an offcut from the project
Save a piece with both face grain and an exposed end. If your project includes very different-looking boards, test more than one. Prepare the sample with the same tools and sanding sequence you intend to use on the furniture. A beautifully polished sample tells you little about a cabinet that received a different preparation.
Make the piece large enough to see a real patch of grain. Tiny colour dabs can hide uneven absorption and make two similar shades look identical.
Record each decision
Label the back with the species, final sanding grit, product names, colour and date. Add the application method and number of coats. If you test a conditioner, note its product and the interval before staining. Keep product instructions with the sample rather than relying on memory.
Change one variable at a time. For example, compare conditioned and unconditioned areas using the same stain, or compare two colours over the same preparation. Changing the sanding, conditioner and stain at once makes it difficult to learn which change helped.
Include the topcoat
Do not choose the colour from stain alone. Apply the intended compatible topcoat according to its directions and allow the stated drying time. General Finishes, for example, gives product-specific preparation and coating instructions for its water-based systems; those instructions should not be treated as a universal recipe for every finish.
Look at the completed sample in the room where the piece will live, during daylight and under the room's lamps. Place it beside flooring, upholstery or other wood that will be nearby. The right choice is a relationship between materials, not simply the darkest square on the bench.
Keep the chosen sample after the project is finished. Store it with the exact product information and an untouched offcut. If you later make a matching shelf, repair damage or build a second chair, those two small pieces can save a great deal of guessing.
