Hola! The amazement of the day: I learned how to make a baby hem by hand on light and not very light fabrics!! :) never knew that you do not need the little metal extra attachment for your sewing machine, but just can do it yourself! perfect: you save a planet by not buying another metal thing, you save 5$, and now you less depend on any kind of "stuff"! You just start by folding the fabric edge and make sure to control the rolling all the time. great. suggest all and everyone: try.
