Like I said before. I have made many of the slings from this pattern. They are fairly easy to make and so far the most comfortable sling I have found. It comes with very clear sewing instructions and great instructions on how to wear it and examples different positions for baby. I used this with my 2nd daughter from the time she was a newborn (practically, I used it in the hospital) and she’s a 21 month old and I still use it sometimes when I’m in a pinch.
