Aren't these cute? They're made from the tops of old knitted socks (these ones specifically).
All you do is cut the top 4 1/2 inches off of an old clean sock. Turn the sock inside-out, and fold over a 1/2 inch of fabric from the bottom (cut edge). Sew in place using a zigzag stitch. Re-invert, and voila! a stylish and rustic drink cosy to jazz up your coffee, tea or hot chocolate :)
