Ok so I have a pattern that calls for worsted wool weight yarn, and size 13 needles, and you're supposed to use 2 strands at once. The problem is that I can only find worsted wool thats thin (like normal yarn thin) and the result I get is very "fishnet like". Extremely loose! Are there thicker yarns that I should be using? The pattern does call for felting at the end, which I've never done before. Does felting get rid of this fish net looseness? Help!
