Notes

  • Flag consists of two layers: Front and Back. One is mirror reflection of another.
  • Flag is worked down top in rows, according to chart or witten pattern. Each row counts 40sc. End each row with ch1, that does not count as stitch, then turn your work and proceed with the next row.

How to read written pattern

← Row 7 [RS]: A15, B12, A9 

  • Arrow indicates direction of row.
  • RS means you work on the right side.
  • Letter indicates which color of yarn to use.
  • Number indicates how many sc of each color to work. Therefore, for this example, you’ll work 15sc in color A, 12sc in color B, 9sc in color A. Then ch1, turn your work and proceed with Row 8.

If you prefer, use chart, each square represents 1sc.

Changing colors

When next sc is marked as a different color on the chart or written pattern, make the last yo of current st with new color and continue with new color, leaving previous color on the WS and pick it, when it appears again. That’s the Fair Isle technique. HERE you can find help with crochet colorwork.
