While most of the prayers can be recited from the book, or from altar cards--or, for the prayers at the foot of the altar, from a prayer card--there are prayers you really have to memorize. So, I did what we used to do way back in high school; I created flash cards, and I carry them around so I can work on them throughout the day.
One of the things I did when I was in the seminary--when I had other prayers to memorize--was to make up some tune to accompany the prayers.
I'm sure some people would be horrified if they heard the ditties I've composed for several of these prayers; perhaps others would be amused. But I would bet I'm not the first one to do it.
Please pray for this old dog learning "new" tricks!
