To begin, knot the end of a length of twine on a corner of the frame, then begin wrapping the twine around the front and back of the frame. You'll need at least 6 lengths on both sides...you can always add more, but the number will need to be even. Knot the end at the frame's corner and cut the twine.
Now weave in the herbs...gently, but securely, push them up so they're snug against the row above. As herbs dry, they shrink...weaving them tightly will help keep them in place. You can also weave in flowers that dry well...globe amarath and sedum are very pretty and add a bit of color.
When you're weaving is complete, turn the frame over. Cut through the center of the loose lengths of twine on the back and gently remove the frame. You'll have at least 6 pairs of twine...one on each side of the stick. Pair one up from the front and back and knot securely. Continue with the remaining pairs along the bottom; repeat with the top pairs.
Yay, you're done! And don't let the lengthy instructions scare you off...it's really easy and you'll be done in no time at all!
