What is Mosaic Crochet

Mosaic crochet is a colourwork technique that uses simple stitches to create beautiful, intricate-looking patterns. Despite its detailed appearance, it’s surprisingly beginner-friendly because you only work with one colour of yarn per row, reducing the need for frequent yarn changes. The magic lies in strategically placed stitches, often UK double or treble stitches, which build up bold geometric designs, stripes, and motifs that look far more complex than they are to make. Mosaic crochet can be worked in different styles, such as overlay or inset, each offering its own unique finish, making it a versatile and rewarding technique for crocheters of all levels.

The Difference Between Overlay & Inset

Overlay

  • Stitches worked into the blo only of the current row or the flo only of the stitch 2 rows down.
  • Pattern work in one row of each colour without turning.
  • Yarn tied off at the end of each row which created lots of ends.

Inset

  • Stitches worked into full stitch.
  • Pattern worked in 2 rows of each colour turning at the end of row.
  • Yarn is not tied off so there aren’t lot’s of ends and you can ‘float’ up yarn.

    I’m interested, but wish there were a text version. I’m just not keen on video tutorials.

    Hi bella coco
    With the insert mosaic when you do the treble down in the chain two space are you going through the front loop or are you going through the stitch it self?
