AcuSetter makes it possible to arrange the position of designs using an iPad before embroidering on the Janome Memory Craft 15000 and Skyline S9. Even if the fabric shifts a little when it is inserted in the hoop, reinserting it isn't necessary. By taking a photo of the embroidery hoop with the fabric inserted in it, the design can be easily arranged while checking various fabric conditions (shifting of the fabric's position, fabric patterns, embroidery already sewn, cross lines etc.).
AcuSetter is Free in the App Store.
