Harry’s Blanket is written in 5 sizes, but it is easily adaptable for extra sizes/inbetween sizes as with all patterns in the ebook.

Sizes:
45x58/65x80/86x107/98x134/117x158cm
Yardage: 350/650/1200/1700/2400m
DK Yarn is used, however, as the pattern is written by row an stitch any size yarn may be used, although yardage would vary. A size smaller needle than suggested on the yarn would be appropriate.
