There's nothing quite like wearing a coat you made yourself — especially when it's crafted from beautiful, high-quality wool. Sewing a wool coat is one of the most rewarding garment projects you can take on, and with the right fabric and a little preparation, it's more achievable than you might think.
Choosing the Right Wool Fabric
The fabric you choose will make or break your coat. For a structured, tailored look, reach for a premium coating wool blend — these are heavier, tightly woven fabrics that hold their shape beautifully and drape with elegance. Browse our Premium Coating Wool Blends collection for options that work perfectly for outerwear.
If you prefer a softer, more relaxed silhouette, a flannel wool or a plaid coating fabric can give your coat a cozy, classic feel. Check out our Plaid Fabrics collection for some gorgeous options that are trending this season.
Wool-Weight Selection at a Glance
Match your fabric's drape and thickness to your pattern, not just its weight label. Light, medium, and heavy are relative categories; a light coating can still be too bulky for a dress. Follow your pattern's recommended fabrics.
| Weight | Best-matched projects | Lining notes | Interfacing notes |
|---|---|---|---|
| Light | Lightweight dress wool or suiting for dresses and fluid trousers; light coating for soft jackets. | Consider a lightweight lining for comfort or opacity; follow the pattern. | Use lightweight support at collars, waistbands, and closures without stiffening the drape. |
| Medium | Tailored trousers and jackets in suitable suiting; transitional coats in medium coating. | A smooth lining helps jackets and coats slip over other layers. | Choose compatible woven or sew-in support for facings, collars, and waistbands. |
| Heavy | Winter coats, peacoats, and structured outerwear; generally too bulky for dresses or trousers. | Choose a durable, smooth lining; allow room for layers and avoid unnecessary bulk. | Support lapels, collars, and closures selectively; trim and grade seam allowances. |
Test lining and interfacing on a scrap first. If using fusible interfacing, check that the heat and adhesive do not mark the wool or change its texture. Product weights quoted per linear yard depend on fabric width and are not directly comparable with weights per square yard.
Shop Fabrics for Your Jacket or Coat
These fabrics are currently in stock in our coating collection. Check the product page for current availability and your pattern for the yardage needed.
- Red Blazer Wool Light Coating: a softly draping, flannel-weight option listed at 10 oz per yard and 62 inches wide, for a lighter jacket rather than a substantial winter coat.
- Brown Sugar Wool Coating: medium-weight, 100% wool with a basket weave and soft drape, listed at 14 oz per yard and 45 inches wide, suited to a swing jacket.
- Bluebell Blue Coating Wool Blend: a heavier, tightly woven 70% wool and 30% nylon coating, listed at 16 oz per yard and 58 inches wide, for a warm coat with soft drape.
How Much Fabric Do You Need?
This is one of the most common questions we get — and the answer depends on your pattern and size. As a general rule of thumb:
- Short coat or jacket (hip length): 2.5–3.5 yards
- Mid-length coat (knee length): 3.5–4.5 yards
- Full-length coat: 4.5–6 yards
Always check your pattern envelope for the exact yardage, and buy an extra quarter yard as a buffer — especially with plaids or stripes that require pattern matching.
Essential Supplies
- Wool coating fabric (see above)
- Lining fabric (silk, bemberg, or polyester)
- Interfacing (woven, sew-in interfacing works best with wool)
- Sharp dressmaker's shears
- A pressing cloth and tailor's ham
- Heavy-duty thread in a matching color
- Coat buttons or toggles
Key Techniques for Sewing Wool
Press as you go. This is the single most important tip for sewing wool. Use a damp pressing cloth and a hot iron to set every seam before moving on. Wool responds beautifully to steam and pressing is what gives your coat that professional, tailored finish.
Use the right needle. A size 90/14 or 100/16 universal or microtex needle works well for most coating wools. Replace your needle frequently — dull needles can snag or damage the fabric.
Finish your seams. Wool can fray, so finish raw edges with a serger, zigzag stitch, or Hong Kong seam finish before assembling your coat.
Hand-baste before machine sewing. Wool can shift during sewing. Taking the time to hand-baste key seams (especially the collar and sleeves) will save you from frustrating misalignments.
Caring for Your Finished Coat
Once your coat is complete, proper care will keep it looking beautiful for years. Most wool coats should be dry cleaned or hand washed in cold water with a gentle wool wash. Always lay flat to dry — never hang a wet wool garment, as it can stretch out of shape. For more detailed guidance, see our post on Washing Recommendations for Fabric.
