I'm doing the same test knit as J-J. I decided to not only because I love the pattern but the general idea seems to be to follow the pattern and use the tools and methods you want. It starts with a provisional cast of choice and no requirement of a specific one. I agreed to follow the pattern when I took on the test knitting, totally my decision and choice, so ithere are no designer control freaking issues to contend with. I knew I'd be following the pattern. I soon realized I can do the cables thus far without a cable needle so again, my choice. After a huge amount of frustration because sometimes I just miss something it's been enjoyable so far. I'm not sure I can meet the deadline but I'll do my utmost to finish on time.
