A tea box is a manageable weekend project, but the sliding dividers need a little planning: loose slots let leaves mix, while tight slots make rearranging a chore. This plan makes a lidded box with removable dividers, sized for common tea bags. You can adjust the interior later without cutting new grooves.

1. Set the dimensions and layout
The example box has outside dimensions of 12 inches long, 9 inches wide, and 3 inches high. With 1/2-inch-thick sides, the inside measures about 11 by 8 inches. That gives room for four compartments across and two rows front to back. Check the tea bags you plan to store before committing: folded envelopes and individually wrapped bags vary in size.
Plan for a removable grid made from 1/8-inch-thick divider strips. Each strip has a series of slots, so the pieces interlock rather than relying on permanent partitions. The grid sits inside the box and lifts out as one assembly. This is easier to change than fixed dividers and simpler to build than a system of routed tracks.
2. Choose materials and tools
Use straight, dry hardwood or good-quality plywood for the box. Maple, cherry, and birch are practical choices; 1/4-inch plywood is also fine if you want to keep the cost down. Avoid strong-smelling or resinous woods for the interior, and let any finish cure fully before storing tea. The lid can be solid wood or plywood.
For the grid, 1/8-inch plywood is more stable than very thin solid-wood strips, which can split at the slots. A 1/8-inch birch plywood sheet is a convenient option if you do not have suitable offcuts. You will also need wood glue, sandpaper, a saw, a square, clamps, and a drill or brad nailer. A set of small bar clamps helps hold the box square while the glue sets; careful clamping with whatever you own works too.
| Choice | Advantages | Trade-off |
|---|---|---|
| 1/4-inch plywood box | Affordable, stable, quick to cut | Exposed edges need sanding or edge banding |
| 1/2-inch solid wood box | Durable, attractive edges | Costs more and needs careful fitting |
| Removable slotted grid | Compartments can be resized | Slots take time to fit accurately |
| Fixed dividers | Fast and sturdy | Compartment sizes cannot be changed |
3. Cut the box parts
For the example dimensions, cut a 1/2-inch-thick bottom at 12 by 9 inches. Cut two long sides at 12 by 3 inches and two ends at 8 by 3 inches. The ends fit between the long sides, so the finished footprint remains 12 by 9 inches. If using thinner stock, revise the end length to account for the side thickness.
Dry-fit the parts on a flat surface and check both diagonals. If the measurements differ by more than 1/8 inch, adjust the fit before glue-up; a skewed box can bind the lid and the removable grid. Sand inside faces now, when access is easy. For a simple butt-jointed box, apply a thin bead of glue, clamp the sides around the bottom, and check square again. Small brads can hold the assembly, but do not rely on them to correct a poor fit.
4. Make the adjustable dividers
Measure the box’s actual interior after assembly. Cut two long strips to the inside length and three cross strips to the inside width. For this layout, the strips should be roughly 2 1/2 inches tall—below the lid—and fit loosely inside the box. Leave about 1/16 inch of clearance at the ends so seasonal humidity changes do not jam the grid.
Mark slot positions along each strip. The long strips need slots for the cross strips; the cross strips need matching slots for the long strips. Space the slots according to the compartment sizes you want, such as roughly 2 3/4 inches apart across an 11-inch interior. Each slot should be centered on its mark, extend halfway down the strip, and be just wide enough for the measured thickness of the mating piece. Test the fit on scrap first. A slot that is too narrow may split the plywood; one that is too wide makes the grid wobble.
Cut the slots with a fine saw, jigsaw, or scroll saw, then pare or sand them to fit. A scroll saw offers control for repeated narrow cuts, but it is not necessary for a small grid. Assemble the pieces without glue, slide the grid into the box, and check that it sits flat. Trim any high spots rather than forcing the assembly.
5. Fit the lid
The simplest lid is a flat panel that rests on top of the box. Cut it slightly larger than the opening—about 1/8 inch of overhang on each side—and sand the edges smooth. Attach two small hinges, keeping them set back evenly from the ends. Check that the lid opens without rubbing the back edge.
A sliding lid looks tidy, but it requires accurate grooves in the long sides and a thin, flat panel. Choose it if you already have a safe way to cut consistent grooves; otherwise, the hinged lid is more forgiving. A poor sliding fit can bind as wood moves, especially if the groove has little clearance.
6. Sand, finish, and test
Sand exposed surfaces through 120 and 180 grit, easing sharp corners lightly. Remove dust before applying finish. For the box exterior, a thin coat of water-based polyurethane or hardwax oil is suitable. Keep finish out of the divider slots, and follow the product’s cure time rather than relying on “dry to touch.” Tea can pick up odors from uncured coatings, so leave the box open in a ventilated room until no smell remains.
Load the compartments with the largest tea bags you expect to store, then lift and replace the grid a few times. If bags catch on rough edges, sand the dividers. If the grid shifts, add a thin strip of felt beneath its outer edges or remake it with slightly less clearance. The aim is a box that stays neat in daily use but still lets you change the layout when your tea collection does.
