Cover with Masking Paper

What happens here

Take a roll of brown masking paper and position it so that one edge aligns with the painter's tape already applied to the cabinet frame. Press the paper firmly onto the tape, ensuring good adhesion. Unroll the paper to cover the entire open area of the cabinet, extending past the taped perimeter. Use a utility knife or scissors (not shown but implied for efficient work) to cut the paper to the appropriate length. Once the paper is covering the opening, use additional strips of painter's tape to secure all remaining edges of the masking paper to the previously applied perimeter tape. Overlap the tape slightly onto the paper and firmly press it down to create a complete seal, protecting the cabinet interior from any paint overspray or drips.

Goal: Completely seal off the cabinet interior from paint.
