I have created a PDF guide on how to make an Orthodox prayer rope, or komboskini. You can find a link to it at the top of this page. I hope it helps, and I am always open to suggestions!
From a hymn of the Church:
The arena of virtue is open. Let all who are willing to compete enter, girding themselves. For those who genuinely compete will be deservedly crowned. Let us do battle with the enemy. Let us take on the armor of the Cross, having Faith as an invincible rampart, prayer as our breastplate, and charity as our helmet.
