Sometimes simple is best.
Pattern: Fiar by Irish Girlie Knits
Yarn: Black Trillium Fibre Arts Gradient Set in Flutter
Needles: US #6 (4.0 mm) Hiya Hiya Sharp Interchangeable
Mods: The pattern includes instructions for a 3-stripe or 5-stripe color sequence but the gradient set works with the pattern repeat of 20 rows. Each mini-skein of yarn yielded 20 rows of knitting so I just knit in pattern until I was about to run out of yarn and added the next color in at a garter section. I ended up running out of yarn right at the bind off so I pulled some white Dale of Norway Baby Ull out of my stash to finish off the bind off on the palest color section (you can hardly tell!). This pattern makes great social knitting as well as being a terrific sock yarn stashbuster. I used all 635 yards of my gradient set but if you have partial balls of sock yarn it would be a fantastic scrappy sock yarn project.
