Built by a craft mom, for craft makers

“Hi! As a mom of two crafting during quiet evening hours, I was tired of wasting limited time and materials guessing plaster ratios. I built PlasterHub to speed up my own production process, eliminate material waste, and ensure every batch turned a profit. Now, I want to share it with fellow makers.”
