Two-stranded heels and toes make these socks super strong. Also, the slip-stitch pattern with one multi-colored yarn and one solid colored yarn makes a cool plaid effect.

I spent all summer designing socks for my hearty, umm, out-doorsy neighbor who had helped up so much in the garden of our new house. Nothing was big enough and no heel/toe was strong enough. After much playing around with slip stitch patterns, I incorporated two strands of yarn and created my own two-stranded heels and toes. The plaid effect from the colours was a complete surprise but is now one of my new stand-bys.
