Product Information

Full details

The Minerva Core Range Pure Boiled Wool Coating in terracotta is an exceptional choice for garment makers and crafters seeking a heavy, warm, and structured textile for seasonal outerwear. Ideally suited for sewists crafting unlined jackets, coats, capes, and hats, this dense, felted wool provides professional-grade results without the need for complex internal construction. While its substantial 400-415 gsm weight offers excellent insulation, users should note that its felted nature requires specific handling during cutting and seam finishing to maintain its clean, fray-resistant edge.

FAQs

Does this fabric need to be lined?

No, the dense felted texture of boiled wool is typically smooth and comfortable against the skin, making it excellent for unlined garments.

Can I wash this in a washing machine?

It is not recommended. Boiled wool can felt further or shrink significantly if exposed to water and agitation; dry cleaning is the safest care method.

Is this fabric stretchy?

It has very little mechanical stretch. It is best suited for structured, non-fitted garments.

How should I finish the hems?

You can leave the edges raw for a clean, modern look, or use a simple whip stitch if you want a more traditional finish.

Will this fabric be warm enough for winter?

Yes, its heavyweight 400-415 gsm rating makes it a highly effective insulator against cold weather.

Can I iron this fabric?

Use a low-heat steam setting and a press cloth to avoid crushing the fibers or leaving shine marks on the surface.

Troubleshooting

Needle skipping stitches during sewing

Increase the stitch length and ensure you are using a new, sharp needle specifically sized for heavyweight fabrics.

Bulky seams making pressing difficult

Trim the seam allowance close to the stitch line, as boiled wool does not fray, and press the seam open using a clapper to flatten the fibers.

Fabric sticking to the presser foot

Use a walking foot or a Teflon presser foot to ensure smooth movement under the needle.

Pros and Cons

Pros

  • High thermal retention for winter garments
  • Does not require lining due to its dense, comfortable texture
  • Extremely easy to work with as it resists slipping during cutting
  • Edges can be left raw for a modern aesthetic
  • Rich, consistent terracotta color

Cons

  • High weight may be too bulky for delicate or draped designs
  • Requires professional dry cleaning to maintain integrity
  • Not suitable for close-fitting garments due to thickness
  • Limited stretch compared to knit wool alternatives

Setup, Compatibility & Care

Working with Minerva Pure Boiled Wool requires minimal specialized equipment, but attention to seam bulk is necessary.

Sewing Setup

  • Needles: Use a universal or sharp needle size 90/14 or 100/16.
  • Thread: Use a high-quality polyester or wool-blend thread for durability.
  • Seam Construction: Since the fabric is thick, avoid heavy seam allowances. Use 'butterflied' seams or, for a cleaner look, trim seams close to the stitching line as the fabric will not fray.

Care Instructions

  • Cleaning: Dry clean only to prevent shrinking and pilling.
  • Storage: Store in a cool, dry place away from direct sunlight to preserve the richness of the terracotta color.
  • Maintenance: Use a wool comb periodically to remove any surface pills caused by friction.
