Step 6: When you are finished scroll-sawing the pattern, soak the snowflake in mineral spirits for a few minutes to loosen the spray adhesive. Peel off the paper pattern and remove any glue residue. Allow the wood to dry.
Step 7: Clean up the straight edges of your snowflake and remove any burn marks with files and sandpaper (see Photo 5). An oscillating detail sander, such as the Multi-Max by Dremel, can speed this process up considerably. Be sure to clamp the snowflake to your workbench and support it carefully during the cleanup process to avoid breaking the delicate wings and points.
Step 8: Next, cut a round base for your trivet from a contrasting-colored wood. Make the base about an inch larger than the snowflake to form an overlap. Mill a chamfer or roundover profile around the top edge of your base with a router or rotary tool and a profiling bit (see Photo 6). Round over the bottom edge, and sand the routed edges smooth.
Step 9: Sand the faces of the snowflake and base up through the grits to 180-grit. Center the snowflake on the base, and use strips of masking tape to mark its position. Then, spread a thin coat of glue on the back of the snowflake, keeping the glue away from the edges of the pattern to avoid squeeze-out (see Photo 7). Set the snowflake in place on the base. Attach it with a few pin nails, or clamp the parts together until the glue dries.
Step 10: Apply a protective finish to the trivet. A thin, penetrating finish is a better choice than a thick surface coating for this project, since the finish must be reasonably heat-resistant. A good option is to blend equal parts mineral spirits and oil-based varnish together. Use a small craft brush to flood the finish onto the wood, working the finish into all the nooks and crannies (see Photo 8). Let the finish soak in for a few minutes, then wipe off the excess with a soft cloth. Repeat the process when the finish dries.
Step 11: Cut a circle of felt to line the back of the trivet. Glue the felt in place, stretching and smoothing it with a block of wood (see Photo 9). Your snowflake trivet is now ready to blow into your next wintertime meal!
