First Efforts

 From the left: standard White thread tied at the bottle neck, Gray rag knitting worsted, White thread over the entire bottle.

Obviously the one on the left isn't covering a wine bottle but I only have two "bottle models" right now. At any rate, from the left: Gray knitting worsted, multi-colored heavy cotton thread, White thread with a ruffle at the top (I think most new designs will include a ruffle).
