These are just too fun. When I saw granny square slippers on this site http://www.purlbee.com/granny-square-slippers/
I knew I had to make them. I did not follow the pattern exactly. I used double crochet instead of single crochet and used only two colors as opposed to several. I really like the color combo she used on hers, but for my first time making them just wanted to use something I had on hand and really like the aqua/brown combo.
As you can tell from the pictures it only takes six granny squares. I used a G crochet hook and Red Heart yarn. I went around once with the aqua color, once with the brown, then two more times with the aqua.
http://www.purlbee.com/granny-square-slippers/ she had her squares 4 1/2 inches from tip to tip diagonally, mine ended up being 5 inches, but the slippers were a little loose for my size 7 feet so will stick with the 4 1/2 next time.
I joined the squares using single crochet and in order to connect the squares I highly recommend going to the Purl Bee website to follow her instructions because her squares are different colors and it is easier to instruct which square goes with which square. I will do my best to explain it, mainly with pictures.
This is a little confusing. Attach the two sides that I have marked with yarn in the pic on the left, which will look like where I started joining the two sides in the picture on the right. Once finished with step 7, it will look like the picture below. This is the top of the slipper.
Step. 8 Now continuing from where you are at, flip the slipper over to the bottom, and continue joining the two squares (top and bottom) to each other working diagonally to the middle of the bottom of the slipper, like the picture below.
The end of step 8should look like the picture below. Cut the yarn.
Step. 9 Flip the slipper over to the top, join new yarn and connect the toe square to the sole square, up one side and down the other. I forgot to take pictures of this step but the end of step 8 should look like the picture below. Cut the yarn.
Step 10. Now you are going to join the heel square to the bottom sole square, up one side and down the other. I start and end a little further up than the corners so it looks like the picture below. Giving it a more snug feel.
Step 11. Continue single crochet up and down the sides of the heel square, cut the yarn.
Voila! You have granny square slippers! Again I thought these were fun to make, look fun, and are comfy.
