This pattern contains both written and pictures. It is easy to follow step by step.
The directs are for one square that measures about 12 1/2 by 12 1/2. There is directs how how to join the squares together. Putting 20 squares together will make a nice size afghan. 4 square wide and 5 square length.
I did not include any gauging for this pattern. The size is approximate depending how you crochet.
I used Red Heart Super Saver Jumbo yarn for my afghan, but any medium 4 weight will look nice.
This pattern calls for 4 different colors, 2 of each except for black.
