Hi, I'm fairly new to knitting and am trying to plan my first afghan. I have gotten the Lion Brand Homespun yarn and want to knit with two strands of this together as one. I have circular needles in size 15, 17 and 19. I did up some swatches and find that the knitting on size 19's is much too loose for what I like.
What I am wondering is... are there guidelines out there somewhere regarding what size needle to use when knitting with two strands of bulky yarn? I want the blanket to be warm for sitting on the couch, but not too heavy/hot so that it won't get used. I guess I'm having a hard time judging what a whole blanket will look like based on a 4x4 square. Any tips are appreciated!
