I am stitching a yucca cactus. The base of the plant has long lines fanning out. The instructions say to long stitch with 1 strand. There are 4 different colors which will form the bottom part of the plant...pretty. But does the needle go thru at the top of the line back to front, carry the thread down to the bottom, and then put the needle thru to the back of the stitching. And then the fan at the bottom will be a series of loose straight threads anchored at the top and bottom, nothing else anchoring them?
