Questions

What is the difference between C2C and a graphgan?

C2C (corner to corner) is worked in small square tiles on the diagonal, starting from one corner. A graphgan is worked in rows of single crochet, one stitch per square of the graph. Single crochet stitches are wider than they are tall, so the graph uses wider cells.

How do I read the C2C row instructions?

Each line gives one diagonal row, starting from the corner you chose, as color and tile counts in the order you work them. "Row 5: 2 Y03, 3 Y12" means two tiles in Y03, then three in Y12.

Which yarn colors are these?

The graph uses a set of common yarn shades with their own codes. Match each one to the closest shade in the yarn you buy; the swatches show the color to look for.

How big will my blanket be?

That depends on your yarn, hook and tension. Crochet a small swatch, count the tiles or stitches in 4 inches, and enter them under Blanket size and yarn.
