Sew Steady Cabinet Inserts by Dream World are designed to provide a custom fit for your specific make and model of sewing machine and cabinet. They are custom made to fill in the gaps around your sewing area to create a flush surface.

The Sew Steady Inserts are made with one of the highest grades of acrylic. To order your custom made insert, you must provide the required information as shown. Without the make and model of your machine, the brand of your cabinet, the size of your opening and other related information as requested, the order can not be processed.
