PDF sewing patterns are so easy to use and fit so well. Do you ever wonder just how they are created? I made this fun video to share with you exactly how we run our testing process here at Ellie and Mac Sewing Patterns. We thoroughly test each pattern so that you get an great fit and quality pattern each time! Each pattern from conception to finish takes 25 - 30 days before we can release the pattern. We have a great schedule that keeps up on track and a huge group of talented seamstresses who work hard to help perfect each one. It takes a tribe to make this Ellie and Mac successful!! They all put in a lot of time, fabric, energy and their ideas into each test. I am so thankful for each team member!!
