How to Sew Wool Fabric: Tips for Cutting, Pressing, and Stitching

Wool is one of the most beautiful fabrics you can sew with, and I'm about to put that to the test with a peacoat project. Here's everything you need to know before you sew with wool, including how to prep it, cut it, set up your sewing machine, and get those seams looking polished and professional.

I am getting ready to sew myself a wool peacoat for church, and I am SO excited about it. I want a belted style, and I just ordered some beautiful wool coating fabric from Amazon. If you know of a good peacoat pattern with a belt, please let me know in the comments!

While I'm in the planning stages, I thought this would be the perfect time to share everything I know about sewing with wool. It can feel a little intimidating, but wool is actually a wonderful fabric to work with once you know the basics.

About Wool Fabric

Wool is made from the hair of sheep or other animals like alpacas. It's super absorbent, breathable, and has excellent insulating properties, even when wet. That's why it's such a popular choice for winter coats, tailored suits, and fine knitwear. It's a fabric that has been used in high-end garments for centuries.

Preparation and Care

Before you do anything, check the care instructions on your fabric bolt. Most wool is dry clean only. Even if it is, you can still preshrink it by steaming the fabric and allowing it to dry flat naturally before cutting.

When pressing during construction, always use steam and a damp press cloth. Don't press too hard. Let the steam do the work for you, otherwise you risk flattening the texture of the wool.

Layout, Marking, and Cutting Tips

Wool often has a nap (a directional texture), so use the "with nap" layout option in your pattern instructions. If you're working with a plaid wool, buy extra fabric for matching the plaid across seams.

Before laying out your pattern pieces, fold your fabric with right sides together and straighten the ends. Pin your pattern using long, sharp pins like quilter's pins, which are sturdy enough to hold through thick coating fabric without bending.

Transfer pattern markings to the wrong side of your fabric using tailor's chalk or tailor's tacks. Always test your marking tools on a scrap first to make sure the marks can be removed cleanly from the finished garment.

Sewing Machine Setup

You don't need a special sewing machine to sew wool, even heavy coating fabric. You just need the right settings.

Setting	Recommendation
Needle	Universal needle size 80/12 or 90/14 for most woven wool. For heavy coating layers, try a sharp or jeans needle in size 100/16. For wool knits, use a stretch or jersey needle.
Presser Foot	Straight stitch foot or zigzag foot, depending on your stitch.
Stitch Length	3.0mm to 4.0mm. Always test on scraps first. For wool knits, use a stretch stitch or narrow zigzag so your seams move with the fabric.

More Tips for Sewing Wool

Finish your raw edges. On unlined garments, finish all raw edges with a serger or seam binding tape. Wool can fray and it will look much cleaner inside.

Make sample buttonholes. If your pattern includes buttonholes, always test them on a scrap of the actual fabric first. For a couture touch, bound buttonholes look beautiful on tailored wool jackets. Just make sure your buttons have a shank thick enough to accommodate the fabric layers at the buttonhole.

Use the right pressing tools. When pressing seams open, use a seam roll to avoid leaving imprints on the right side of your fabric. A tailor's ham is invaluable for shaping curved seams and steaming jacket lapels into their final form.

Wool is one of those fabrics that rewards the extra time you put into it. The results look genuinely high-end, and there is nothing quite like wearing something you made yourself out of a beautiful wool fabric.
