Triquetra - (1 Loop Triquetra) by Margaret Bremner, CZT / Enthusiastic Artist. "Steps 1-5 are done in pencil. These lines act as your string. Step 4 shows the looped line in red, just so it's clear. Step 5 shows the entire pencil string. Step 6 is when you start using ink. The short ink lines indicate what goes over and under. I've drawn them bolder. The connecting lines that you draw later are dotted".
