Enhance Your Library's Aesthetic: A Guide to Adding Trim to Bookshelves
How to Upgrade Bookshelves
Bookshelves are more than just functional storage units; they're a reflection of your personal style and a canvas for your literary journey. Adding trim to bookshelves can elevate their aesthetic appeal, creating a cohesive, polished look that ties your space together. Here's a comprehensive guide to help you achieve this transformation.
Adding Trim To Cabinets & Bookshelves
Understanding Trim: Types and Materials
Trim refers to the decorative border that frames your bookshelf. It can be as simple or as elaborate as you like, depending on the look you're aiming for. Here are some common types and materials:

Before you start, measure your bookshelf's height, width, and depth. This will help you determine how much trim you need and where it should be placed. Also, consider your bookshelf's style - modern, traditional, or somewhere in between - to ensure your chosen trim complements it.
Choosing the Right Trim for Your Bookshelf
Selecting the right trim involves balancing aesthetics with practicality. Here are some tips:

For a cohesive look, match the trim's finish to your bookshelf's existing hardware or the room's decor.
Thinner trims are best for modern, minimalist styles, while thicker, more ornate trims suit traditional or rustic spaces.
Consider the scale of your bookshelf. A large bookshelf can handle thicker, more substantial trim, while a smaller one may look overwhelmed by it.

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.

Now that you've got everything ready, it's time to transform your bookshelf. Here's how:
Measure and cut your trim pieces using a miter saw. Make sure to account for the thickness of the trim when measuring.
Sand any rough edges or surfaces to ensure a smooth finish.
Apply paint or stain (if not prefinished) to your trim pieces, allowing them to dry completely.
Using a Brad nailer, attach the trim to the bookshelf. Start with the top and bottom pieces, then move on to the sides.
Use a level to ensure your trim is straight and even.
Once all the trim is attached, fill any nail holes with wood filler, sand smooth, and touch up with paint or stain if necessary.
Congratulations! You've successfully added trim to your bookshelf, elevating its look and adding a personal touch to your space.
