I've been sewing ribbons in soft shoes for 8 years now by folding down the heel then sewing the ribbon slantwise along the fold. Is it the same with pointe shoes? I've looked on Youtube and some do, but most seem to sew them so that they are a right angles to the shoe. HELP! I can't ask her teacher because she needs them for Monday! And does she automatically need elastics or are they just if they slip? HELP again!
