Love my Maggie Frames. I use the 12.6 x 3.9 when I do sleeves or get inventive and use it on this "Wifey" sweatshirt embroidery. Recently started up a new custom embroidery business and am loving the Maggie frames because they hold fantastic, are quick to use and easy to make accurate if you are doing multiple shirts with same embroidery on them. They are definitely a time saver. And no more hoop burn!
