When my daughter Snowflake ❄ started wearing pointe shoes(Age nine),I also started learning to sew them. Here is some tricks i learned from other ballet moms (that have older ballet daughter than mine). Here is step by step procedure how I do it.
Above is additional materials you need for sewing the pointe shoes.
》I used dental floss as thread to sew the garter and the ribbon because its more durable and its not penetrating on the outer layer of the other side of the pointe shoes.
》 I use lighter to burn both ends of the garter and ribbon so it wont snag.
》 Putting rubber/leather capping(Optional ) on the tip of the pointe shoes to make it last(I usually put it before but instead my daughter use Leukoplast (plaster used in injuries)
