Answer:
I have a little house in which I live all alone. My house has no doors or windows and if I want to go out I must break through the wall.
I can be winding and I can be straight. I can be smooth and I can be rough. Sometimes both. I start out black but fade to brown. My favorite colors are yellow and white and I love stripes and dashed lines.
I have feathers that help me fly; with head and body but I'm not alive. Very skinny and a fixed length how far I go depends on your strength.
Without a bridle, or a saddle, across a thing I ride a-straddle. And those I ride, by help of me, though almost blind, are made to see. What am I?
I am bought by the yard but worn by the foot
What do you purposefully put lots of in and on your body, but run away from when you encounter it outside?
