Stabilizers and hooping
Hoop burn (hoop marks), explained
Hoop burn usually comes from hooping tighter than the fabric needs or leaving it in the hoop for a long time. A light steam, a wash or brushing the nap often lifts it, though delicate fabrics can stay marked. Many embroiderers avoid it by floating the item on adhesive stabilizer or by using a magnetic hoop, which clamps without the same crushing ring; the hooping guide covers prevention and removal.
