After reading about St. Thomas Aquinas, I became curious about something I had seen mentioned often in the Fr. Greeley novels I had been reading: the rosary. What is a rosary? A google search quickly answered that question. The rosary is a prayer, combining repetitive vocal prayers and meditating on the life of Christ. It's also the Divine Office for the poor and uneducated; the 150 recitations of the "Hail Mary" correspond to the 150 psalms.
I was intrigued. I wanted one. But how to get one? I could have easily ordered one online, but that would have necessitated the use of my credit card, and my parents at least had the ability to look at my bill (I doubt they ever really did; they're just not like that), and because I was still uncertain where all this was going, I didn't want to be answering any questions about what I bought from some Catholic company online. I didn't know that there was a Catholic bookstore in town, or I'd have been there in a heartbeat. I didn't even know such things existed.
My solution? I found instructions to make a knotted rosary online (at Rosary Army). I found the twine at Walmart and a crucifix at Hobby Lobby. My first attempt was pretty sad looking. My second attempt was much improved -- the knots were much closer together and uniformly spaced. I carried it in my pocket all the time for the next several months, so it spent a lot of time as a tangled mess. I even prayed it a few times, but not often, because I couldn't remember all the prayers.
