How To Change A Baby Jumpsuit Into Open-crotch Pants

1. Prepare tools such as sewing machine, sewing needle, sewing thread, scissors, etc.
2. Determine the position to be modified, usually at the bottom of the baby's onesie, at an appropriate distance from the crotch.
3. Use scissors to cut the onesie along the determined position, and then separate the two legs.
4. Use a sewing machine or hand sewing to sew the cut parts.
