Step 1: Step 1 Supplies
There are very little needed in way of supplies. You first need to decide how many skeins of yarn you will need. Since these will be felted, they will look HUGE when first assembled, but will shrink down to size when washed, and dried.
I wear a Woman's US size 8.5, so I decided to go with the suggested size block for a size 9, which was 20 single crochet stitches across, and 20 rows for each block. I probably could have made it a little smaller, and it still would have been OK.
NOTE: I had VERY little left over from each shein of yarn (the supply picture shows how much was left), and in fact, had I done this in the pattern shown on the video, I would not have had enough of one color. IF you wear a larger shoe than this you WILL need more than 2 skeins
2 skeins of 100% wool yarn (I used Patons Classic Wool 100g/3.5 oz)
Crochet Hook (I used a G) US
