I am an av-aid sewer, I also have over 200 spools of embroidery thread. I am thinking this would be an awesome idea to have an app for people who sew. I am talking about Machine embroidery thread, regular thread, quilting thread - I know this app would be handy by many people - It woulld be nice to be able to scan the barcode and it automatically keeps track of your thread. I know I have duplicated colors more than once - I hate having to carry a sheet of paper to look through to see which colors I have - They do have the charts in excel format to view - but that takes away the whole point of being able to just check the app and find out - you have that thread.I have quite a bit of thread - I can't rermember what numbers or colors I have all the time. Brands like Sulky, Mettler, Guterman, Coats & Clark, Robinson Anton and the list goes on..I'm thinking I would pay to have an app like this - all the time it would save me.
