Granny Chevron Blanket
This pattern gives you an estimate of how large to make for a throw blanket, but can easily be made larger/smaller by adding/removing sections or crocheting more/fewer rows.
Can even be worked up in a thicker/thinner yarn of choice.
The examples have been worked with 2 skeins each of 4 different colors, but can also be made with 1 color or up to 16 (if following the pattern sizing).
Many options to make it your own!
