Frequently Asked Questions
Q: Can the Brother BM3850 handle heavy fabrics like denim or canvas?
A: Yes. With the correct denim or heavy-duty needle size and proper tension adjustment, the BM3850 can reliably sew through multiple layers of denim, garment leather, and home decor fabrics.
Q: Is the extension table removable, and how securely does it attach?
A: The wide extension table slides on and off easily in place of the standard free-arm accessory storage compartment. It features sturdy, adjustable legs to ensure a completely flat, stable sewing surface.
Q: Does this machine allow you to lower the feed dogs for free-motion quilting?
A: The BM3850 uses a darning plate (included) that fits securely over the feed dogs. This bypasses the feed mechanism, allowing you to manually move your fabric in any direction for free-motion embroidery, quilting, and monogramming.
Q: What type of bobbins does this machine use?
A: The machine utilizes standard SA156 Class 15 plastic bobbins. Using the correct clear plastic bobbins ensures the quick-set jam-resistant system operates perfectly.
