Regarding question #2 - the bracelet was started as three separate strands of E6-1 that were woven into a relatively loose braid (let's call these strands A, B and C). However, when closing the bracelet, instead of connecting the ends A-A, B-B and C-C I connected A to B, B to C and C to A (you might need to play with the number of overlaps you make when weaving the braid). Once connection was done this way, the bracelet ended up having just a single continuous strand of E6-1. I pulled out and removed a portion of this strand to adjust the final bracelet size.
Hope this helps.
