Sandpaper Effect
how abrasion leads to transformation
Nobody tells you how much of carpentry is sanding.
You picture the saw, the square, the satisfying thunk of a joint coming together. But a surprising share of the work is quieter than that: standing over a board, moving a block of grit back and forth, watching rough fibers turn to dust. Sixty grit, then one-twenty, then two-twenty. Each pass removes the marks the last one left behind, until the wood under your palm feels less like lumber and more like skin.
I've been thinking a lot lately about what that process has to teach us about healing.
Friction is not the enemy
We tend to treat abrasion as something to avoid. The hard conversation, the season of loss, the job that grinds you down, the body that won't do what it used to. We brace against it, or we try to skip ahead to the smooth part.
But sandpaper doesn't work without friction. The roughness is the tool. What feels like wearing down is often a slow revealing: the same grain was there all along, waiting under the splinters and saw marks.
Psychology has a name for a version of this: post-traumatic growth, the observation that people sometimes come through hardship with deeper relationships, clearer priorities, and a stronger sense of meaning. It isn't a promise, and it doesn't make pain worth it. But it suggests that difficulty can do more than just damage us. It can shape us too.
Work with the grain
The first thing you learn when sanding is to follow the grain. Go across it and you leave scratches that disappear under the dust, only to show up loud and clear the moment you apply a finish.
Years of massage work taught me the same lesson in a different material. Tissue doesn't release because you force it. It releases when it's met: when pressure follows the direction the body is already asking to move. Push against it and the body guards, tightens, holds on harder.
Healing has a grain, too. Yours might not look like anyone else's. Some of us soften through movement, some through stillness, some through talking it out, some through making something with our hands. Working against your own nature might look like progress for a while, but the scratches show up later.
You can't skip grits
Here's the part every apprentice learns the hard way: you can't jump from coarse paper straight to fine. If you go from 60 to 220, the fine grit can't erase the deep scratches the coarse one left. It just polishes them. You have to move through each stage in order.
Transformation works like that. The coarse grits are the big shifts: the move, the ending, the decision you couldn't take back. They're fast and loud and they take a lot off at once. The fine grits come after: the daily, almost invisible work of tending to yourself. Rest. Boundaries. Breath. Showing up again tomorrow.
Both matter. And neither one can do the other's job.
The first plateau
I'm closing in on my second year as a carpentry apprentice, and I'll be honest: lately the progress feels slower. The early months were all coarse grit. Every week brought a new tool, a new term, a new skill I couldn't do on Monday and could by Friday. Now the gains are quieter. I'm repeating cuts I already know how to make, trying to make them cleaner, faster, truer.
Anyone who has learned a craft knows this place. Skill doesn't grow in a straight line. It climbs, levels off, and climbs again. The flat stretches feel like standing still, but they're often where the last lesson is settling into the hands. It's the fine-grit phase: less dramatic, but it's what makes the surface ready for finish.
Plenty of apprentices don't make it to year two.
The work is physically demanding, the learning curve is steep, and the plateau is exactly where it's easiest to decide this path isn't for you. Making it here doesn't mean I've arrived. It means I've reached the first of many plateaus, and I'm learning to treat it as a landing rather than a wall.
Know your material
This past weekend I spent two days in an oncology massage training, and one idea keeps following me into the shop: there are no contraindications, only considerations. A well-trained therapist doesn't turn someone away because they're in treatment. They adapt pressure, position, and session length. During chemo, the touch stays very light, and deep tissue work waits up to a year afterward, because the body needs months to clear what treatment leaves behind. The effects also build with every cycle, so the person on the table today isn't quite the person who was there three weeks ago. The work isn't about treating a disease. It's about meeting the individual person in front of you, as they are that day.
Wood asks for the same attention. A thin veneer can't take the grit or pressure that rough-sawn oak can. Press too hard and you sand right through it, and there's no taking that back. Good sanding starts with reading the material.
The part that stuck with me most was about scar tissue. Research on fascia suggests that fibroblasts, the cells that rebuild connective tissue, respond to very low-tension movement. So once a surgical scar has fully healed, the work isn't to push hard into it. It's to gently lift and move the tissue around it, again and again, and let it reorganize on its own time. Gentle and consistent beats forceful. That sounds a lot like an apprenticeship, and a lot like any healing worth doing.
Some seasons call for coarse grit. Some call for the gentlest touch you have. Learning to tell the difference is the craft.
Bite Sized Offering: A small ritual: what is this smoothing?
The next time something rubs you the wrong way, pause long enough to ask 3 questions:
What grit is this?
Is it a coarse season, taking a lot off at once, or a fine one, asking for patience and small steady passes?Am I working with my grain or against it?
What does my body want to do right now, and am I listening?What might be underneath?
If this friction is revealing something rather than only wearing me down, what could it be?
You don't need answers right away. Sometimes just naming the grit is enough to stop fighting the paper.
From the workbench
I am poetic by nature, but abrasive and transformative, like sandpaper. I've stopped apologizing for either half. Out here in the woods of upstate New York, between the shop and the treatment table, I keep finding the same truth in different materials: what's whole was never hidden very deep. It just needed some patient, honest friction to come through.
Repair, it turns out, is a kind of ritual.
Happy reading, and happy sanding.
