English beading needles in sizes 10 and 12 are the best choices for use with size 11 seed beads. You can also use a size 10 sharps or short beading needle for these beads if you need to maneuver through a tight spot. Big eye needles and twisted beading needles can also be used, but their slightly larger size won't allow for quite as many thread passes.
Nylon beading threads in medium to heavy weights work very well with these beads. Gel-spun or fishing line type threads can also be used with great success. Remember that heavier threads will allow for fewer passes through each bead, so the stitch will ultimately determine whether you should use a smaller beading needle or not.
