I crocheted this blanket as one piece, but it could be done
with the seasons as individual panels. Included is a pattern
for the blanket as a whole, and the individual seasons.

To use yarn or hook size other than those called
for in this pattern:

Crochet the first three squares. Do not cut the yarn, but
hold your place on the yarn and pull out the squares.
Measure what was used and divide by 3. This is the number
of inches you will need per square. Multiply this by the
number of squares per color (listed below). Divide by 36 to
give you the total yardage needed for each color.
