For this you will need 3 colors of yarn, I am using red, green, and white Red Heart Yarn which was her favorite to use for the project.
Size J crochet hook
yarn needle
To start your first granny square with red yarn chain 3 and make a loop,
Round 1: ch 2, make 2 DC in the loop, (ch 1, do 3 DC in the loop), repeat 2 times, ch 1 slip st to the top of the ch 2, tie off. You will need 15 of these, I find it faster to just work with one color and do all the squares at once.
Round 2: with green working in the corner ch 1 space, ch 2, 2 DC, ch 1 3 DC in the first corner, ch 1 move to the next corner and do 3 DC, ch 1 3 DC, repeat in the next two corners, ch 1 sl st in the top of the first ch 2, tie off.
Round 3: with white and starting in the corner ch 2 2DC, ch 1 3DC, ch 1 3DC in the center ch 1 space, then the next corner 3 DC, ch 1 3DC, ch 1 3DC, ch 1 repeat ending with a ch 1 sl st to the top of the ch 2. For this round I leave a long string to use to sew the squares together as I go.
For the heel of the stocking make 1:
Round 1: chain 3 in red and make a loop. Ch 2, make 2 DC in the loop, ch 1, 3 DC, repeat once, ch 1 sl st to the top of the ch 2.
Round 2: in green, ch 2, 2DC, ch 1, 3 DC, ch 1 then 3 DC, ch 1, 3DC ch 1 repeat in the next corner, ch1 and sl st to the top of the ch 2. Tie off and switch to white.
Round 3: working in white, ch 2, 2 DC in the first corner, ch 1 3 DC in the same space, ch 1 3DC in the next ch 1 space, ch 1 3 DC ch 1 DC in the next corner, repeat around, ch 1 sl st to the top of the first ch 2. tie off leaving a long string.
