5 Common Mistakes with Bone Folders & Folding Tools (And How to Avoid Them)

As a passionate artisan bookbinder based in Edinburgh, I’ve spent countless hours in my workshop, wrestling with the nuances of folding and creasing. The tools we use, particularly bone folders and other folding instruments, can make or break our projects. While these tools might seem straightforward, I’ve learned through trial and error that they can become sources of frustration if not handled correctly. Here, I’ll share five common mistakes I’ve encountered with bone folders and folding tools, along with my tips on how to avoid them.

Mistake #1: Ignoring the Right Tool for the Job

When I first started, I assumed that all folding tools were interchangeable. I would grab whichever one was nearest without considering its specific purpose. This was a costly error. A bone folder is fantastic for creating sharp creases, while a Teflon folder is better for delicate papers that require less friction.
💡 Clara Hensley's Rule of Thumb: Always assess the type of paper you’re working with. For thicker papers, use a bone folder; for lighter, more delicate papers, reach for a Teflon folder.

Mistake #2: Using Excessive Force

I can’t tell you how often I’ve pressed down too hard with a bone folder, thinking it would yield a more defined crease. Instead, it often led to paper damage, tearing, or unsightly marks. The key is to apply even, gentle pressure. For instance, I’ve found that a steady, soft stroke with the folder is far more effective than a heavy-handed approach. A light touch allows the fibers to bend without breaking, preserving the integrity of the paper.

Mistake #3: Neglecting Maintenance

In my early days, I didn’t think much about maintaining my tools. Over time, I noticed that my bone folder was becoming rough and less effective. This can happen due to the natural oils from your hands or the occasional contact with adhesive. To keep my bone folder in top condition, I now make it a habit to clean it regularly. A simple wipe with a damp cloth and a gentle polish with beeswax keeps it smooth and functional.
Maintenance Task Frequency Notes
Wipe down bone folder After each use Use a damp cloth, avoid soaking
Polish with beeswax Monthly Apply a small amount, buff with a soft cloth
Check for damage Every few uses Look for nicks or rough spots

Mistake #4: Overlooking the Importance of a Cutting Mat

When I first began, I often folded papers directly on my workbench. This was a mistake I quickly learned to avoid. Not only did it leave marks on my desk, but it also compromised the quality of my folds. A good cutting mat provides a stable surface that helps guide my folds and protects my tools. I recommend investing in a high-quality cutting mat that’s thick enough to absorb pressure but thin enough to allow for accurate measurements.

Mistake #5: Not Practicing Proper Technique

When I first picked up a bone folder, I was eager to jump into my projects without fully grasping the technique. I discovered that the angle at which you hold your folder and the direction of your crease can significantly impact the outcome. I suggest practicing on scrap paper before tackling your main project. This allows you to experiment with varying angles and pressure, helping you develop a feel for the tool.
What is the best type of paper for using a bone folder?
I find that heavier papers (like cardstock) respond beautifully to bone folders, yielding sharp, clean creases. Lighter papers can also be folded with these tools but may benefit from a lighter touch or a Teflon folder.
How do I know when to replace my bone folder?
If you notice nicks, rough edges, or a lack of smoothness on the surface, it might be time to replace your folder. A well-maintained tool should glide effortlessly across the paper.
Can I use my bone folder for bookbinding?
Absolutely! Bone folders are essential in bookbinding for creating sharp creases in signatures and covers. Just remember to use them gently to avoid damaging the paper.
As I reflect on my journey, I’m grateful for the lessons learned along the way. Each mistake has been an opportunity for growth, allowing me to refine my technique and improve my craft. By avoiding these common pitfalls with bone folders and folding tools, you’ll be well on your way to creating beautiful, professional-quality work. Whether you’re just starting your journey in bookbinding or have been at it for a while, I hope these insights help you avoid some of the frustrations I faced. Happy folding!
