Ahh, Unit Six. You made it to the top level. You have a variety of basic skills that you are really good at. Now you can try "the hard stuff". Jeans. Shirts with collar and cuffs. Skirts with a proper waistband. Jackets with labels and bound buttonholes. Trousers with pleats. Unit Six is currently in development, which gives you plenty of time to finish Units One through Five first!
