Fleece is a knit, so it wants a knit needle — and it is forgiving about almost everything else.
Use a ballpoint or jersey needle, 80/12 or 90/14. A universal point cuts the loops.
Use a stitch with give — a narrow zigzag or a stretch stitch. A straight stitch on a fleece seam snaps when stretched.
Lengthen the stitch to about 3 to 3.5 mm. Fleece is bulky and short stitches perforate it.
Do not press it. Most fleece is polyester and melts or mats under a hot iron. Finger-press seams, or use a very cool iron with a pressing cloth if you must. This is the mistake that ruins fleece garments.
Seam finishing is optional. Fleece does not fray, so a plain seam is perfectly durable. Many people leave edges raw, which reduces bulk.
Reduce bulk where you can. Grade seam allowances, and consider a lapped seam rather than a conventional one on thick fleece.
Expect lint. A great deal of it. Clean the machine afterwards.
And it stretches more in one direction than the other — check before cutting, and run the greater stretch around the body.
Questions people actually ask
Do I need a walking foot?
It helps on thick fleece where the layers creep. On lighter fleece a jersey needle and a longer stitch are usually enough.
Which side is the right side?
Often hard to tell. Stretch the cut edge across the width: it usually curls towards the right side. Then mark every piece as you cut.
