Setup, Compatibility & Care
When sewing this fabric, use a sharp, medium-weight universal or jeans needle (size 90/14 or 100/16) to ensure consistent stitch quality through the layers. Utilize a slightly longer stitch length (3.0mm to 3.5mm) to accommodate the fabric's thickness.
Because boiled wool is prone to shrinking if agitated in water, it must be dry cleaned. If you need to pre-treat, some sewists opt for a gentle steam press with a pressing cloth to stabilize the fabric before cutting. Avoid heavy ironing with high heat directly on the surface to prevent crushing the felted texture; always use a pressing cloth and a "wool" or steam setting.
