DIY Piano Key Wood Coasters
These coasters use contrasting hardwood scraps to create a simple piano-key pattern that makes a small project feel much more intentional.
They are a good batch project for leftover maple, oak and other hardwood offcuts because the pieces are small, repeatable and easy to make as a set.

Turning Small Hardwood Scraps Into a Finished Set
Coasters are a useful way to use narrow offcuts that are too small for larger projects. The piano-key pattern adds visual interest without requiring complicated joinery.
Creating the Pattern
The design depends on contrasting wood tones. Narrow strips are arranged to mimic piano keys, glued into a larger blank and then cut down into individual coasters.
Maple and white oak work well together because the color difference creates a clear pattern while still keeping the finished set natural and understated.
Batching the Coasters
Once the process is set up, multiple coasters can be made efficiently. Building one larger patterned blank first helps keep the dimensions and layout consistent across the entire set.
After the glue cures, the blank can be trimmed into individual coasters and brought to final size before sanding.
Finishing
A durable clear finish protects the wood from moisture while keeping the natural contrast between the species visible.
Because coasters see regular contact with drinks and condensation, sealing the faces and edges helps keep the wood stable and makes the finished set easier to maintain.
This is a small project, but it is a good example of getting more value out of scrap material instead of throwing useful hardwood away.
