The Brother SA221CV Hemming Set is designed for the Brother Coverstitch machine to help you create clean, professional hems on knitwear, jersey, activewear, children’s clothing and other stretch fabrics. The set includes specialised attachments that guide the fabric smoothly, maintain even folding and support consistent stitching - ideal for achieving that polished, ready‑to‑wear finish found in commercial garments. By stabilising the fabric and controlling the fold, the SA221CV reduces tunnelling, waviness and stretching, which are common challenges when hemming knits. It’s especially useful for T‑shirts, leggings, dresses, sportswear and curved hems, where precision and fabric control matter most.
