I have made five chain ladder rosaries, four of them for four of my six children. The first one took me all day with painstaking struggles to get it right. The second one went smoother, and by the time I finished the fifth, it took me just a few hours. I didn't have instructions, just a ladder rosary my sister had given me years ago as a model.
I use 8mm beads. I just ordered more beads and eyepins from OLRM and am going to make another 10 in the hope of selling them, maybe at my local church, to help support my mission rosary making.
If I could figure out how to attach pictures, I'd show you the ones I have made, they include an emerald green, purple, orange, pink, and pinkish/purple. The first four are in my children's favorite colors with crucifixes and centers chosen especially for them; the last one was just because I had the supplies and is now an extra.
I'd be happy to share how I made mine if you're interested.
Also, if someone knows a better way to go about selling rosaries to help support their mission work, please let me know.
