Before you start, it's crucial to select the right trim for your bookshelf. The trim should complement the style and color of your bookshelf and room. Here are a few options:
Wood Trim: This is a classic choice that can match or contrast with your bookshelf, depending on the look you're going for.
MDF Trim: This is a more affordable option that can be painted or stained to match your bookshelf.
Plastic Trim: This is a durable, low-maintenance option that's great for modern or contemporary styles.

Applying the Trim
Start by applying wood glue to one end of a trim piece. Align it with the top edge of the bookshelf and secure it with brad nails or finish nails. Use a nail set to sink the nails below the surface, then fill the holes with wood filler if necessary.

Repeat this process for the other trim pieces, ensuring they fit snugly and the mitered corners are flush. Use clamps to hold the trim in place if needed.

If you include the flooring and the fireplace build, this project has taken me just over a year to complete and I cannot wait for it to be done. Last time we left off, I had installed my cabinets and built four separate shelving units out of oak boards and I decided to stain my shelves to try to keep some natural wood on this project. I got the best looking thin plywood that I could find for the back of these shelves. I didn't want super thick plywood because then my shelves would stick out too far. I started attaching all my backs and realized very quickly that I was just building a playground attached. I also primed and painted all of these back pieces before attaching them so I wouldn't have to tape off my stained shelves to paint them later. After going through far more paint samples than I want to admit or that I ever want to see again, I finally decided on a color and went ahead and started priming and painting all of my cabinets. I usually like to prime by hand because primer can really clog up your paint sprayer and let's be honest, I just don't have my life together enough to clean my sprayer fast enough for it to not get clogged. So, I used a brush for the edges and then a foam roller for all the flat pieces to prime the cab and then I use my paint sprayer to spray the actual paint on the fronts and the backs. I attached all my shelves into the studs and the walls and now it was time to add some trim to make up for all of those uneven walls and maybe some mistakes. The one side of these shelves is exposed into the dining room so I decided to add a little bit of his shaker style trim around that side to give it a little bit more character instead of just a plain wall. Since no wall is ever straight, I had to use a level on every single one of these trim pieces to make sure that my trim was actually straight and not lining up against the wall and we'll fix that with the caulk later. Filling nail holes and caulking really isn't that bad but I was sick at the end of this project so this is probably my least favorite part of this entire process. This part and the rest of the painting really only took a couple days but since I was sick, it felt like an eternity. Now, before you come at me for painting this wood, I had to use a different type of wood on the trim pieces than I did for the shelves so if I stained them, they wouldn't match. I added battery-powered picture frame lights to the top of these units and then some gold handles to finish it all off. I am so happy to almost be done with this living room project. And I love how it turned out but I'm so ready to put my furniture back.DIY Ikea Bookcase Makeover (No Powertools) - Hattie KolpOur Dream DIY Built-in Bookshelves on a Budget - The Gage Made Home10 Thrifty Reclaimed Wood Projects | Confessions of a Serial Do-it-YourselferHow to add molding to a bookcaseDIY Bookcase Tutorial (DIY built in, all the details!!)
Once the trim is secure, sand any rough edges or surfaces. If you're staining or painting the trim, do so now. Allow the stain or paint to dry completely before handling the bookshelf.
Adding trim to a bookshelf is a simple DIY project that can significantly improve the look of your space. With the right materials and a bit of patience, you can achieve professional results. Happy trimming!
