Connect Your Squares

Using Color C, Sandwich 2 squares together and SLST the first CH. SLST the BLO for the remainder of the side of the square. Connect the rest of your squares with the SLST method. I’ve created a chart for you to know which squares to connect together

The black, white, and pink/blue granny square top is laid out on a wooden table, near the brown crochet hook used to make them, and a little journal with dogs on the cover.

Create The Strap 

Using color C, SLST to the edge of the top of the square. CH 50. When finished, SLST the CH to the other corner of the square that makes up the top portion of the tank top.
