Baby Tiger is done in the interlocking filet crochet method.
the gauge is not really important, the thinner the yarn and smaller the hook the smaller the blanket will be and the heavier the yarn and larger hook the larger the blanket will be. This one done with worsted weight and 5.5 mm(I) hook came out 36” x 36.“
You will need two different colors a dark and a light and use about 750 yards of each color.
I used Hobby Lobby crafters Secret one-pound skeins and a 5.5 (I) hook.
I had about 70 yards left in each color.
