Start by planning your knot on paper, and when you've arrived at an arrangement you like, transfer it to the garden spot (a full-sun location is essential) with lime or a water-based spray paint that's designed for marking the ground.
Rosemary makes a good border plant; other good hedge herbs include lavender, hyssop, rosemary, sage, thyme and winter savory. For fillers, you can use whatever you want, depending on what your favorites are and their availability when you're planting your garden.
Plant the rosemary in a hole that's the depth of its container. Be sure to insert the rosemary into the hole so the top of rootball is even with or slightly above soil level. Space border plants one per 1' for small herbs, one per 2' for large herbs. Plant the filler herbs. Once the plants start to grow, trim them several times a year; also, it's a good idea to keep spare border plants on hand in other areas of the garden in case some in the knot die. Wherever you plant your knot, though, remember that herbs love a good pruning: the more you clip, the more lush and attractive your herbs will grow to be.
