Minky is a soft polyester pile knit, and it does two awkward things at the same time — it stretches on the crosswise grain and its pile makes the layers slide.
Fit a walking foot. This is close to essential. Without it the top layer travels and a long seam finishes several centimetres out of alignment.
Pin far more than you think you need, every few centimetres, or use clips. Pinning through pile is what stops the shift a walking foot cannot fully take out.
Use a stretch or ballpoint needle, 80/12 or 90/14, and lengthen the stitch to about 3.5 mm.
Check the stretch direction before cutting and note it on every piece. Minky usually stretches across the width and barely along the length.
Widen the seam allowance to about 1.2 cm if the pattern allows. Minky creeps and a narrow allowance can slip out of the seam entirely.
Never press it. It is polyester pile: the iron mats and melts it, and the mark is permanent. Finger-press, or topstitch the allowances down.
Pair it with a stable fabric for blankets — quilting cotton on one side, minky on the other — and quilt or tie the layers so the minky cannot travel.
Expect a very great deal of lint. Cut over a bin, vacuum afterwards, and clean the bobbin race before your next project.
Questions people actually ask
Why does my minky seam come out crooked?
The layers shifted. A walking foot plus close pinning, and sewing with the minky underneath where the feed dogs control it, fixes most of it.
Do minky edges need finishing?
No, it is a knit and does not fray. Reducing bulk matters more than neatening.
