Make a Hardwood Pen Tray with a Routed Groove and Felt Lining

A hardwood pen tray is a small project, but it rewards careful layout. A shallow routed groove keeps pens from rolling, while a felt-lined recess protects the finish on a desk or nightstand. The build uses one hardwood blank, a trim router or router table, and a few simple shop tools. Plan on two to four hours, including glue-up and finish drying time.

Materials and tools

Start with a hardwood board about 3/4 inch thick, 4 to 5 inches wide, and 12 to 14 inches long. Walnut, cherry, maple, and oak all work. Avoid boards with knots near the routed areas; a knot can chip out or make the groove look uneven.

You will also need a small round-over bit, a straight or core-box bit for the pen groove, sandpaper from 120 through 220 grit, wood glue, finish, and thin adhesive-backed felt. A trim router is convenient for this project, although a router table gives better control if you already own one. Use a sharp bit no larger than 1/2 inch for the groove.

For a budget build, ordinary craft felt and a wipe-on finish are perfectly adequate. The felt is replaceable, and the tray is unlikely to see standing water or heavy abrasion. Spend more on a sharp router bit rather than premium felt.

Size and layout

Cut the blank to 12 inches long by 4 inches wide. Slightly round the corners with a compass or a small round object, or leave them square for a more formal look. Mark the centerline along the length of the tray. The pen groove should run parallel to the long edges and sit about 1 inch from the front edge.

Make the groove 1/2 inch wide and approximately 1/8 inch deep. A pen should rest in it without touching the desk. If you plan to hold thick markers or a stylus, increase the width to 5/8 inch and test the depth on scrap first. Leave at least 3/4 inch of wood between the groove and each end; narrow end sections are more likely to chip.

For a tray with a separate felt-lined storage area, mark a shallow rectangular recess behind the groove. A practical size is 8 by 2 1/2 inches, centered across the tray. The recess only needs to be 1/16 to 1/8 inch deep—just enough for the felt to sit nearly flush. Do not make it deeper than the felt thickness unless you want a visible step around the lining.

Route the pen groove

Clamp the blank to a workbench with scrap under the clamps to prevent dents. Make a simple router guide from a straight board if you are using a handheld router. Position the guide so the bit follows your layout line, then check the distance at both ends. A router guide is safer and more repeatable than trying to steer freehand along a pencil mark.

Set the bit depth for a first pass of about 1/16 inch. Run the router from left to right when the guide is on the router’s left side, keeping the base pressed firmly against the guide. Make a second pass to reach the final depth. Do not remove the full 1/8 inch in one cut; that encourages tear-out and can pull the router off line.

Use a core-box bit for a rounded-bottom groove. A straight bit works, but it leaves a flat bottom with sharper corners and is less comfortable for a single pen. If the groove ends are square, finish the rounded ends with a small chisel. Otherwise, stop the router before the ends and leave them naturally rounded.

Cut the felt recess

Mark the recess with a sharp pencil or knife. Set the router depth to 1/16 inch and take multiple shallow passes. A straight bit works well here. Keep the corners rounded unless you are prepared to square them with a chisel; forcing a square-cornered router path often leads to overcutting.

Route the long sides first, then remove the waste from the center. Overlap each pass slightly, but do not leave ridges between them. A flat sanding block can smooth minor marks, but sanding too aggressively may make the recess uneven. Vacuum all dust before fitting the felt.

Shape and sand the tray

Ease every outside edge with a 1/8-inch round-over bit or a few controlled strokes of 180-grit sandpaper. A sharp edge chips easily and feels unfinished. If using a router, test the round-over on scrap from the same board; different woods show burn marks at different speeds.

Sand the broad surfaces with 120, 150, and 220 grit. Sand the groove by wrapping paper around a dowel or using a narrow abrasive strip. Do not round over the rim of the felt recess. That edge needs to remain crisp enough to hide the felt border.

Apply finish and install the felt

Apply two or three thin coats of wipe-on polyurethane, sanding lightly with 320-grit paper between coats, or use a hardwax oil according to its instructions. Keep finish out of the felt recess if possible. If it gets coated, let it cure fully and sand the recess flat before lining it.

Once the finish has cured, measure the recess rather than trusting the original layout. Cut the felt 1/16 inch smaller in both length and width. Test-fit it, then peel the backing and press it down from one end to the other. A precision craft knife makes cleaner felt cuts than scissors. If the felt wrinkles, remove it immediately; adhesive-backed material becomes harder to reposition after a few minutes.

Common problems and fixes

Burn marks usually come from a dull bit, excessive speed, or lingering in one spot. Make shallower passes and keep the router moving. Tear-out at the groove ends means the bit was fed in the wrong direction or the cut was too deep. Leave extra material at the ends and trim it carefully after routing.

If the felt sits below the surrounding wood, add a second layer rather than routing the recess deeper. If it stands proud, remove it and trim a little more from the felt edges. Let the finish cure for the full recommended time before placing pens in the tray; uncured finish can transfer to rubber grips and leave permanent marks.
