The rules every mosaic chart follows
- One colour per row, swapping every row: A on odd rows, B on even rows.
- Always the right side, right to left, cutting the yarn at the end of each row.
- Back-loop single crochet for plain squares; double crochet in the front loop two rows below for an X.
- No X on top of an X: a dc always shows its own row's colour, so the generator never needs to stack them.

Questions
What is overlay mosaic crochet?
A two-colour technique where every row uses one colour and the colours swap each row. Most stitches are single crochet in the back loop; a double crochet worked in the front loop of the stitch two rows below lies over the row in between, bringing its colour forward to make the picture.
How do I read a mosaic crochet chart?
Start at the bottom: row 1 is colour A, row 2 colour B and so on, as the strip beside each row shows. Work every row from right to left with the right side facing you. A plain square is a back-loop sc; a square with an X is a dc in the front loop of the stitch two rows below.
Why did some stitches change from my picture?
Overlay mosaic has rules: a dc always shows its own row's colour, rows 1 and 2 and the top row can't have one, and edge stitches are kept plain. Where the picture breaks a rule, the stitch keeps its row's colour. Tap the chart to adjust any stitch.
Do I cut the yarn after every row?
Yes, in rows: you always work on the right side, so you cut the yarn at the end of each row and join the next colour at the right edge. Leave tails long enough to weave in or knot into a fringe.
What yarn should I use?
Two strongly contrasting colours of the same weight. Smooth worsted or DK cotton or acrylic shows the stitches best.
Is it free?
Yes. Make and print as many charts as you like.
