Tools and materials

  • Painter's tape
  • Lumber (appropriate size and quantity for your project)
  • Miter saw
  • Level
  • Measuring tape
  • Pencil
  • Wood glue
  • Nails or brad nails
  • Hammer or nail gun

Planning out the design with painter's tape

1. Plan and Lay Out the Design

Start by visualizing your desired moulding design and use painter's tape to lay out the pattern on the wall. This step allows you to experiment with different arrangements and ensures you have a clear idea of how the finished product will look.

Gathering the lumber for the project

2. Gather Your Lumber

Acquire the appropriate lumber for your moulding project. Choose a type and size of lumber that suits your design and fits well with the room's aesthetics. Make sure you have enough material to create all the required pieces for your moulding boxes.

3. Make 45-Degree Miter Cuts

Using a miter saw, carefully make 45-degree miter cuts on the ends of the lumber pieces that will form the corners of your moulding boxes. Pay attention to the angle settings and double-check your measurements before making the cuts to ensure accuracy.

Using a level to space the moulding

4. Use a Level as a Spacer

To achieve even spacing between the moulding boxes, utilize a level as a spacer. Place the level vertically between each piece of lumber as you position them on the wall. This technique guarantees consistent and symmetrical spacing throughout your design.

Assembling the picture frame moulding

5. Assemble the Moulding Boxes

Apply a thin layer of wood glue to the mitered edges and join the lumber pieces to form the moulding boxes. Secure the corners with nails or brad nails using a hammer or nail gun. Wipe off any excess glue and ensure the boxes are securely attached to the wall.

6. Sand and Finish

Once the moulding boxes are in place, use sandpaper to smooth any rough edges or surfaces. This step ensures a flawless finish and prepares the moulding for painting or staining. If desired, paint the moulding boxes to match your room's color scheme.
