A wooden picnic caddy keeps plates, napkins, cutlery, and condiments together instead of scattering them across a picnic table. This version has a central carrying handle and two or three small compartments on each side. It is simple enough for a beginner, but the finished box looks better when the cuts are accurate and the edges are eased carefully.

Materials and dimensions
The caddy below is sized for a typical family picnic. Its outside dimensions are about 18 inches long, 10 inches wide, and 11 inches high including the handle. The main box is divided into two equal halves, with removable dividers creating condiment compartments.
| Part | Quantity | Finished size |
|---|---|---|
| End panels | 2 | 10 × 10 inches |
| Long side panels | 2 | 18 × 5 inches |
| Bottom | 1 | 17 1/4 × 9 1/4 inches |
| Center handle | 1 | 1 × 2 1/2 × 16 inches |
| Compartment dividers | 4 | 1/4 × 4 1/2 × 8 1/2 inches |
Use 1/2-inch cedar, pine, poplar, or hardwood. Cedar is light and naturally more moisture-resistant, but it is softer and can split around screws. Pine is the cheapest option and is perfectly adequate if the caddy will be stored indoors. For a more furniture-like result, use poplar or oak, though the extra weight is noticeable.
You will also need waterproof wood glue, 1 1/4-inch exterior-rated screws, sandpaper, and an exterior finish. A waterproof wood glue is worthwhile because picnic caddies often encounter damp tables and condensation.
Tools and layout
A table saw makes the repeated strips easy, but a circular saw with a straightedge works just as well. Add a drill, 1/8-inch drill bit, countersink bit, tape measure, square, clamps, and a jigsaw or handsaw for shaping the handle. A portable table saw is useful if you expect to build several projects, but it is not necessary for this one.
Inspect each board before cutting. Avoid pieces with severe bowing or loose knots near screw locations. Mark the best face of every part, and keep the grain direction consistent on the visible panels. Cut the end panels and side panels first, then dry-fit them around the bottom. The bottom is intentionally slightly smaller than the inside opening so it can fit without forcing the sides apart.
Cut and prepare the parts
Cut the two end panels to 10 by 10 inches. On each panel, mark a centered handle opening. A practical opening is 1 1/4 inches wide and 5 inches tall, beginning 2 inches above the bottom edge. Drill a hole at each upper corner, cut between the holes with a jigsaw, and smooth the opening with 80-grit followed by 120-grit paper.
For a less complicated build, skip the cutout and attach a separate handle above the box. The cutout version is lighter and easier to carry, while the separate handle allows a wider grip and avoids weakening the end panels. Whichever design you choose, round every exposed edge slightly. Sharp corners are uncomfortable and more likely to splinter.
Cut the long side panels and bottom. If your lumber is a true 1/2 inch thick, the listed sizes should work. Lumber sold as 1/2 inch can vary, so measure the actual thickness before cutting the bottom. A bottom that is 1/8 inch too wide can bow the side panels outward.
Assemble the caddy
Apply glue to the bottom edges of the end panels and clamp the bottom between them. Check that the assembly is square by measuring both diagonals; adjust until the measurements match within 1/8 inch. Drill pilot holes before driving screws, especially in cedar or pine. Two screws per joint are enough for each end panel, provided the glue is spread evenly.
Add the long side panels next. Apply glue to the bottom and end joints, clamp the panels in position, and drive screws through the sides into the end panels. Keep the screw heads flush or slightly recessed. Wipe away squeeze-out immediately; dried glue can prevent stain from absorbing evenly.
Let the box sit for at least 30 minutes before removing the clamps, then leave it overnight before heavy sanding. If a corner is slightly out of alignment, do not force it with a screw. Remove the screw, realign the joint, and drill a new pilot hole. Forcing a misaligned joint commonly produces a split end panel.
Add the handle and dividers
Round the ends of the handle with a jigsaw, or simply soften the corners with a block plane and sandpaper. Position it between the end panels so there is about 3 inches of clearance above the top edge of the box. Drill through the end panels into the handle, then secure it with glue and two screws on each side.
Make four removable dividers from 1/4-inch stock. Cut shallow slots in opposing divider pairs if you want them to interlock. Otherwise, glue small cleats inside the box to support the dividers. Removable dividers are easier to clean and let you carry taller bottles. Fixed dividers are stronger but limit the usable space.
| Divider style | Advantages | Drawbacks |
|---|---|---|
| Removable | Flexible layout; easier cleaning | Can rattle or shift |
| Fixed | More rigid; no loose parts | Less adaptable; harder to clean |
Sand and finish the wood
Sand all surfaces with 120-grit paper, then finish visible faces with 180 grit. Do not polish the wood excessively; a slightly textured surface accepts finish more evenly. Round the top edges, handle opening, and bottom corners to about a 1/8-inch radius.
For outdoor use, apply two or three thin coats of an exterior water-based wood finish. Lightly sand with 220-grit paper between coats. A clear finish shows the grain, while paint hides inexpensive boards and offers better color options. Do not use ordinary indoor varnish; moisture and temperature changes can make it peel.
Allow the finish to cure according to its label before loading food or containers into the caddy. This is a carrier, not a cutting board, so food should remain in sealed containers. Add a washable liner to the bottom if you regularly carry leaking condiment bottles. A washable non-slip liner is cheaper and more practical than permanently lining the wood.
Seasonal use and maintenance
In spring and summer, keep the caddy shaded when possible; direct sun can warm condiments and accelerate finish damage. After each outing, empty it, wipe spills with a damp cloth, and dry it upright. Do not soak the box or put it in a dishwasher. Before winter storage, check for raised grain, loose screws, or finish cracks. A light sanding and one maintenance coat of finish is usually enough to extend its life.
