I had found the popular Saartjes Bootees pattern on the internet and turned it into a ballet slipper.
These are the modifications that I made.
1 – The bootees are made in pink to row 23 (small size) or 25 (larger size) and then cast off.
2 – The first 2 and last 2 cast off loosely to fit the pink ribbons later.
3 – Attach the pink ribbon, length to your desire.
