Seraflock

Mettler Seraflock is a textured overlocking thread on 1000m spools, designed to add bulk and coverage on overlocked seams and rolled hems rather than strength alone. It comes in a broad colour range, from White, Black and Eggshell through to brighter shades like Hunter Orange, Papaya, Aqua and Deep Purple.

Seraflock is typically used as a looper thread where you want a fuller, more covered finish, such as on rolled hems, decorative overlocked edges or lightweight knit seams. Pick a colour to match or contrast with your fabric depending on whether you want the stitching to blend in or stand out as a decorative edge.

Spools ship same or next business day, so you can top up colours as a project needs them.
