Great for Hard to Hoop Fabric: Even if there are zippers or uneven fabrics, just move the separate magnets to the side area to clamp these kinds of fabric much tighter than the magnetic hoop with one-piece upper frame. Easy Adjustment: Compared with the magnetic embroidery hoops with one-piece upper frame, it is very easy to adjust fabric when already hooped in place. You only need to easily pick up the related magnet and adjust the fabric to get it straight. No need to pull on the entire fabric, which cause the fabric and embroidery to deform or to re-hoop. Anti Fabric Sliding: Add soft coating material to the solid metal bottom frame to avoid scratching the fabric, and prevent the fabric from sliding during the embroidery process
