Joining the split crotch
Joining the split crotch is absolutely optional, but I find that it adds just one more degree of comfort.
It is not a difficult task to join the crotch, but it does take a bit of patience. Placing the crotch under the the needle of the sewing machine is a bit of a challenge, but once the garment is maneuvered into place, it is a simple task to sew the split shut.
The Normal Split Crotch
Rago has a different, patented split crotch. Although there is less likelihood of genital fallout, this crotch is still a bother. In my opinion, the Rago girdle is more comfortable with the crotch sewn together.
The procedure is just a bit different than the previous. With the Rago, you need to wear the girdle then bend over and mark alongside the seam that you will sew together. The photo shows the wearer sitting on a bed so you can see the seam better, but, in reality, you should mark the girdle while standing.
After you sew the seam that you have marked, you must, once again, turn the girdle inside out and sew the opposite seam.
