Black Barbob Type G (Box of 50)

Black Type G Pre-Wound Barbobs, Box of 50

Black Type G Barbobs are ready-wound bobbins for compatible sewing machines, providing a convenient lower-thread supply without having to wind individual bobbins in the workroom.

Supplied in a box of 50, they are well suited to professional upholstery, furniture manufacturing, cushion making, soft furnishings, mattress work and other repetitive machine-sewing applications.

Why Use Pre-Wound Type G Bobbins?

Pre-wound Barbobs arrive ready for use in a compatible bobbin case, helping reduce the time spent stopping to wind fresh bobbins during production.

They are particularly useful for:

• Furniture-cover production
• Cushion manufacture
• Piped upholstery
• Mattress and bedding work
• Soft furnishings
• Repetitive commercial sewing
• Workrooms using the same colours regularly

Keeping prepared bobbins beside the machine can make colour changes and routine bobbin replacement quicker.

Black Bobbin Thread for Dark Upholstery

Black is a useful general-purpose colour for many darker upholstery materials.

It can work particularly well with:

• Black fabric and vinyl
• Charcoal upholstery
• Dark grey materials
• Navy and very dark blue
• Dark patterned fabrics
• Concealed construction seams
• Furniture covers
• Cushion covers

Where the underside of the seam is concealed, an exact colour match may not always be necessary.

However, incorrect stitch balance can allow the lower thread to become visible on the face of the material, so always check a test seam from both sides before beginning finished work.

For furniture and contract coverings, browse Status Fabrics' Vinyl & Fabric range.

Check That Your Machine Takes Type G

The Type G designation refers to the bobbin format and is important when selecting a replacement.

Type G and Type L are not interchangeable simply because the bobbins may look similar.

Before ordering, compare:

• Sewing-machine make and model
• Existing bobbin
• Bobbin-case type
• Overall bobbin diameter
• Overall width
• Centre or core construction
• Thread-delivery direction

If your machine requires Type L, select Black Barbob Type L, Box of 50 instead.

Do not force an incorrectly sized bobbin into the bobbin case, as poor fit can affect thread delivery, tension and stitch formation.

Matching the Bobbin with the Upper Thread

The upper and lower threads work together to create the finished machine stitch.

When setting up the machine, consider:

• Upper-thread construction
• Bobbin-thread compatibility
• Needle size
• Thread tension
• Material thickness
• Number of layers
• Seam construction
• Finished stitch appearance

For strong coloured furniture and upholstery seams, Somabond 40's Bonded Nylon Sewing Thread provides a professional bonded nylon option in an extensive range of colours.

For an alternative construction, see M36 PolyCotton Corespun Sewing Thread.

Always test the complete combination of upper thread, Barbob, needle, material and machine settings before production sewing.

Useful for Cushions, Piping & Zip Panels

Type G Barbobs can be particularly convenient when producing multiple covers using the same machine and thread setup.

Typical operations may include:

• Seat and back cushions
• Cushion borders
• Sofa and chair covers
• Piped seams
• Zip panels
• Mattress borders
• General upholstery seams

For piped furniture and cushion edges, browse Piping Cords.

For removable covers and zip panels, explore the Zipping range.

When sewing through piping or several folded layers, test the thread and bobbin through the thickest part of the intended seam.

Other Type G Barbob Colours

Choose:

• Beige Barbob Type G, Box of 50 for beige, cream and neutral materials
• Brown Barbob Type G, Box of 50 for brown, tan and earthy shades
• White Barbob Type G, Box of 50 for white and pale materials

Keeping several common colours in the workroom makes it easier to select a suitable lower thread without winding fresh bobbins for every job.

Store Barbobs Clean & Clearly Labelled

Keep unused pre-wound bobbins protected from dust, loose fibres, adhesive overspray, oil and workshop debris.

Type G and Type L bobbins should be stored separately and clearly labelled so that similar-looking formats do not become mixed.

For sewing-machine maintenance, 125ml Sewing Machine Oil can be used sparingly at lubrication points specified by the machine manufacturer.

Keep lubricating oil away from thread, bobbins and finished upholstery materials.

Black Type G Barbobs supplied as a box of 50 pre-wound bobbins for compatible industrial and upholstery sewing machines.

Ready-wound bobbins provide a convenient alternative to winding individual bobbins, making them particularly useful for furniture upholstery, cushion manufacture, soft furnishings, mattress work and repetitive production sewing.

Black is used for black, charcoal, dark grey, navy and other dark upholstery materials, particularly where the bobbin thread may be visible on the reverse of the seam.

Type G and Type L Barbobs are different formats and are not interchangeable. Check the sewing-machine specification, bobbin case or existing bobbin before ordering.

For the alternative format, see Black Barbob Type L. Other Type G colours include Beige Barbob Type G, Brown Barbob Type G and White Barbob Type G.
