Step Two: Attaching the trim. This step took longer than I wanted because I had to make sure the trim was securely attached and I didn’t have as many clamps as I needed to make the job go by faster. Because I used a very light weight wood I was able to just glue on the trim. Each time I glued a section of the trim I had to make sure I clamped it securely, otherwise the wood would warp. Once I glued each piece of trim, I filled the gaps with spackling and sanded everything smoothly.
