If you choose to add a custom insert for your table, please note we will need your machine's brand and model number. Each acrylic insert is custom-made to fit your machine and table combination. These inserts are designed to fill the gap between your sewing machine and cabinet opening. This ergonomic work surface will allow for neater stitches, less fatigue, and a better sewing experience! If you order a custom acrylic sewing insert, it will be shipped separately and delivered later than the table since they are custom built.
