Using a sewing machine on denim, especially thick layers, involves preparing the fabric and selecting the appropriate settings.
Based on the provided video reference, one method demonstrated for sewing through multiple layers of denim is by rolling the fabric and sewing through the combined thickness using a normal straight stitch.
Steps for Sewing Rolled Denim
The video snippet illustrates a specific technique for handling thick denim sections, such as hemming jeans. This involves folding and rolling the fabric layers to create a dense edge.
Here's a breakdown of the process shown:
- Layering the Denim: The starting point involves multiple layers of denim. The reference mentions starting with "three layers of denim".
- Rolling the Fabric: These layers are then "rolled" over on themselves.
- Increasing Thickness: The rolling process increases the effective thickness being sewn through. The example indicates the initial three layers are rolled to create six layers of thickness, and then further rolled to reach nine layers of denim thickness.
- Sewing Through: The sewing machine is then used to sew directly "straight through this" rolled, thick section.
- Stitch Selection: The reference explicitly states the machine is set to a "normal straight stitch" for this process.
Essentially, the video shows a technique where thick sections of denim are condensed by rolling, and a standard straight stitch is sufficient to sew through this considerable bulk on the machine being used in the demonstration.
When working with denim, particularly multiple layers, it's generally important to ensure your machine can handle the thickness and potentially use a needle designed for denim or thick fabrics, although the reference specifically uses a "normal straight stitch" without mentioning a special needle type. The rolling technique helps manage the bulk under the presser foot.
