Continuing the discussion from About the SeamlyMe category:
Hi @arorah2001, welcome to Seamly!
From your description, it sounds like you’ve made a measurement file, but not a pattern file. You can find a rather outdated, but still usable tutorial for how to draft a shirt here: Tutorial for making a simple shirt (test) - Seamly2D
There are also several patterns already drafted & free to use if you make an account on the pattern-cloud here: https://my-pattern.cloud/
I hope this helps!
