DIY projects aren't about perfection. Every piece turns out unique, and that's part of what makes it special.

A natural wood workshop means your sign may have random cracks, chips, knots and other natural blemishes that give it character! Some peeling may occur. Fabrics, ceramics, resin, etc. may have minor inconsistencies.

Paint, stain, glue, resin or other materials provided may stain or damage clothes so please dress accordingly, grab your apron, and rollup your sleeves!

We will do our very best to minimize disturbances to your items and make everything look intentional, but due to the nature of the workshop we can make no guarantees.

Please keep in mind, no item is absolutely perfect, as it is hand crafted, but it will certainly be worthy of showing off!
