Unfortunately, we cannot teach you how to make rosaries but there are many great sources available.
To learn about the parts of the rosary:
Below is a photo of the parts on a typical paracord rosary. Numbers 2, 4, 5, 6, 7, 8 may also have just a knot or a bead for the "Our Father".
Some of the rosaries may also have a medallion for the center instead of the big knot at number 9.
1. Crucifix
2. Our Father Knot, or could be a bead.
3. Faith, Hope, and Charity, Hail Mary Knots or Beads.
4. Next large knot: Glory Be, Our Father, or could be a bead
3. Hail Mary Knots or Beads.
5,6,7,8. Our Father Knots or Beads
9. Centerpiece knot area is the end of the rosary. Can also be a Centerpiece medallion.
