You may choose the hook size and yarn weight to your liking. The pattern includes a symbol key and 4 charts. The difficulty level is beginner+.

I used a 1.5 mm hook and yarn with a yardage of 530 m per 100 g. After blocking, the finished piece measures 9 cm measured diagonally for a circular pattern / from side to side for a square pattern). The size of your doily will depend greatly on your tools, materials, and tension.
