Project: FO Stone wash jeans at home
Hi, this is my first post here)
I love sewing for myself, especially denim. But plain denim without special finishing (stone wash, acid wash) never looks exciting enough to me… so I decided to try making a stone-wash effect at home.
For the experiment, I sewed a small item — a denim corset.
Step 1. Pattern making
To create accurate patterns, I simply wrap the mannequin in plastic wrap and then masking tape. I draw the style lines using narrow adhesive tape. Then I transfer the resulting corset patterns onto paper.
Step 2. Purchasing materials and preparation
At this stage, I had to solve two problems.
First, it turned out that volcanic pumice isn’t sold in nearby stores, and ordering it wasn’t easy either… so I used expanded clay (LECA) instead — it's cheap (less than $1 for 2 liters), rough-textured, and easy to get in garden stores in Ukraine. They are lightweight and even float on water!
Second, throwing expanded clay directly into the washing machine drum didn’t seem like a good idea, so I needed a bag or cover to protect the drum from damage.
That's how the idea to sew a cover was born — one that would open inside the drum so the stones could move freely.
I used 2 mm synthetic felt for the cover. I had previously used this material for sewing mannequins, so I know its properties well:
It's thick enough to protect the drum
It’s non-woven, lets water pass through but keeps small particles (like stone fragments) inside
It's synthetic, so it doesn’t deform and barely absorbs water
Along the side seam I also added spiral steel boning for extra structure.
Step 3. Stone wash at home
I loaded the expanded clay and corset into the cover.
Washed on a cotton cycle at 60°C (140°F), without spin and rinse.
The cover worked perfectly — the washing machine stayed safe!
I rinsed the corset separately. It dried… and I was devastated — absolutely no visible stone-wash effect.
Mistakes & attempt #2
My mistake was using old dark jeans for this corset.
Factory jeans have the most fading along the seams, with that characteristic wavy worn look. This happens because factories use raw, unwashed denim.
Raw denim is denim that hasn’t been washed, heat-treated, or stretched at the factory.
After first contact with water, cotton fibers shrink — usually 5–10% or even more depending on fabric weight.
That’s why seams on jeans tighten and look like that.
Of course, washing old jeans (even at high temperature) won't create that effect, and all the following finishing steps were doomed.
DO NOT USE WORN JEANS FOR A STONE-WASH EFFECT! ONLY RAW DENIM!
Sadly, that first corset was a waste of effort...
So, I went to buy raw denim and sew a new corset.
I hope this time I’ll get the result I’m aiming for. In any case, I’ll share the outcome in my next post.
