I designed his multi pattern in hopes to help with establishing the correct sole for either a shoe or a slipper. I did a lot of research came across some that was quite close . I later discovered Craft yarn council and tried basing my pattern on it. I chose Premier Home yarn only simply because it was a new yarn I never used . It was a multi color but feel free to use other colors . Also the hook of preference can be altered it may change the outcome of the product. not a whole lot of material needed the most was 60 yards which is basically a size 5 1/2 shoe size. The sole sizes are as follows …3 1/2 in for newborn to 2 months .. 4 3/8 in for 2 to 4 months…4 3/4 in for 5 to 8 months and for 9 to 12 months was 5 1/4 in…2 to 4 year olds was 6 1/2 in …4 to 6 year olds was 7 1/2 in … while 7 to 12 year olds was 9 1/2 in in length .
