Renderka, Overlock, or Coverlock? What are the differences?

Each of these machines performs a different function, so it's worth knowing which one to choose for your projects.

Render - what is it for?

specializes in ladder stitches, which are perfect for hemming and finishing stretchy fabrics like T-shirts and leggings. Renderka doesn't trim edges, but gives garments a professional look.

Overlock - Where is it used?

Its function is to overcast, sew, and trim the fabric simultaneously, preventing fraying. It's an excellent machine for sewing knits and thin, fraying fabrics.

Coverlock - What is it used for?

This is a combination overlocker and sewing machine, meaning it combines the functions of both devices. It's the best choice for those who want a versatile machine for a variety of applications.
