The Multi-Purpose tool can be used for tools in one!
Use it as a Height Compensation Plate on either the thick or thin side to easily glide over the "hump" when sewing over thick cross seams such as when hemming jeans, etc. The Height Compensation Plate is also useful when topstitching collars, cuffs and other areas where the foot is off the edge and the machine cannot feed properly.
The hole in the Multi-Purpose Tool is used to hold the needle tight when inserting or removing the needle, no more dropping them into the machine! And it helps hold it easily for those with limited mobility in their fingers.
