im a fan of the 360 stretch ribbon b/c they are so much softer and less likely to rub on sensitive skin, causing bloody torsion cuts unlike the unforgiving hard satin ribbons that are soo stiff. I can wear elastic ribbon on bare skin and they are also less likely to rip tights. they are also the only ribbons you can sew in a single loop, that does not involve " tying knots" making it faster and easier to slip pointe shoes on and off. ( though sewing the loop is a skill in itself and can be hard to master if you are a beginner)
