I Built a Browser-Based Pattern-Making Tool for Leathercraft — “Mizushi”

Hello, this is Itsumoarigatone.

I’ve just released a leathercraft pattern-making tool called “Mizushi.”

The project is named “Mizushi.”

It’s a tool for creating patterns directly in your browser.

Because it runs on the web, you can quickly check or work on your patterns anytime —

while commuting, or even when you’re choosing leather.

That’s one of the things I really like about it.

I released it at the point where I can at least create my own patterns,

so it should be usable — hopefully!

Here’s what the workspace looks like.

(I’m wondering if I should add grid lines…?)

This tool is mainly for leathercraft,

but I think it might also be useful for people in fashion or apparel as well.

There are a lot of things I want to build on top of this,

so I’d really love for you to try it out.

Some ideas I have will only make sense once more users start using it. 🙏

Currently, the UI is only available in Japanese, but I plan to support English in the future.

Even so, I hope you can still try it out and share your feedback!
