3) Basic or fancy rosary?
Some rosaries are very plain and basic, and these are always safe bets for giving to new Catholics (the more elaborate or decorative rosaries may be a little too much for them), for children, or for giving out in multiples (to bible study groups, etc). Plain rosaries typically have round beads strung on a thin cord rope and are usually very inexpensive. Plastic rosaries also fall into this category and are good for giving to groups or to children.
However, will the plain, inexpensive rosaries be an encouragement to pray the rosary daily? Or, is a nicely-crafted rosary more likely to do the trick? If you admit that having a beautiful rosary that you absolutely love will encourage you to use it more, then you have your answer!
