From the page: Idle wood wants to become a piece
Idea 1
Corner shelf with joinery
Before cheap screws and wall plugs, countryside woodworkers and carpenters used wooden joinery — cuts that fit together like puzzle pieces — to join parts. The reason is simple: wood "works" with humidity, shrinking and swelling, and joinery follows that movement better than rigid metal, which loosens over time. It is an old technique that still yields more durable furniture today.
What you need
- Mold-free wood board, medium thickness (2 to 3 cm is ideal)
- Fine-tooth saw or coping saw
- Chisel or strong knife (or coarse sandpaper)
- Ruler, pencil, and square
- Screws or nails to fix it to the wall
How to make it
-
1
Cut the board into a triangle or fan shape, with the two straight sides fitting into the wall corner — this removes the need for external brackets, which remain visible.
-
2
On the two sides facing the wall, make a shallow cut (half-lap) to fit into the molding or where the walls meet — the joint distributes the weight and keeps the shelf from spinning.
-
3
Sand the edges well so they do not splinter with use.
-
4
Fix it to the wall with screws and anchors that hold the weight you plan — for books, use 8 mm anchors; for light décor, 6 mm is enough.
-
5
Test the weight with one hand before loading it for real — if it wobbles, reinforce the fixing points.
Finishing touches
rub wax or cooking oil (sunflower, linseed) with a dry cloth for a finish; a small mirror on top flatters the corner.
