I did it! My very first sleeve, thanks to a pair of 16" Addi circular needles in 5.00 and 4.50 mm....yay! I am so happy with how it turned out. I took some artistic license with it and it has a shorter cuff than the original - now some would call it a goof, but no way not me...it just makes mine even more unique and I happen to love the shorter cuff.
I think with how fast this sleeve went that I'll have it done by the end of April, which was my original goal.
