Amazing tool
I know how to draft a basic pattern from scratch but this tool is just amazing to create a fast custom costume with a perfect fit.

The Digitalization I Needed
It is really helping me in my workflow to create custom patterns.
I’m looking forward to trying new patterns as soon as I have the opportunity! I love it.

Amazing!!
The measurements I took resulted in a perfectly sized leotard for my dancer, I didn't have to make a single adjustment. Thank you!!
