I had a lot of fun playing this demo, as a sewer myself. I'm hoping for some more dress variations in a larger release. I had some trouble with the 'quality' stat before I realised it's mainly about how well you cut the fabric. I love how it mentioned the selvedge but I think it could have had a better representation of where that was? The line changed to green when it was both horizontal and vertical for me (and once when it was diagonal), so potentially a white line, like you get with real fabric?
Overall though, I really liked it, please make a full release!
