I am making long pants and it is made in two pieces. There is not much shaping.
Finishing says to sew center front and back seams from top of waistband to marker. sew inseam. Cut elastic 1" more than desired waist measurement overlapping ends 1/2 " sew firmly in a circle. Place elastic along wrong side of waistband , fold waistband to inside and sew in place, being careful not to catch elastic
Once you sew the elastic in a circle and put it over the waistband how do you sew the band over when the elastic is gathering it? Is there a easier way of doing this?
