One of LittleOwlsHut moderators (Sabax/Aino Krog) designed these witches shoes and shared with us. Thank you!

Informations and materials:

These shoes are for a witch that measures 35 cm high,
use 2mm hook for it, and 1,75 mm for the top on the shoe (if your doll is larger or smaller you might have to use other hook sizes, you will know once you have finished the first sole).
For small shoes, I did use Angora deLUX Linate (550m – 100g), a tip is that you should use same yarn thickness as for your witch.
