Dry Fit Mitered Trim and Prepare for Fastening

What happens here

After cutting, the trim pieces are brought to the installation location. One person is seen carrying a long board, suggesting preparation for placement. The video then shows a close-up of two miter-cut boards being brought together to form a corner, demonstrating the fitting process. This step is crucial for verifying the accuracy of the cuts before permanent fastening.

Goal: Ensure mitered trim pieces fit together perfectly at the corner.
