Zak has already approved of the initial set up!
Pattern for those who are interested:
Holding two strands together, Ch 101.
Row 1: DC in second CH from hook, DC in each CH along. 100 SC.
Row 2: CH1. (DC in DC, TR in DC). Repeat (***) until end. 50 DC, 50 TR.
Row 3: CH1 (DC in TR, TR in DC) Repeat (***) until end. 50 DC, 50 TR.
Repeat row 3 until piece is desired length.
I'm changing the colour every 5 repetitions, I have dark brown, a fawn, a tan and a cream. The pattern goes:
Brown/Brown x 5,
Brown/Fawn x 5,
Fawn/Fawn x 5,
Fawn/Tan x 5,
Tan/Tan x 5
Tan/Cream x 5
Cream/Cream x 5
etc etc. You get the picture.
Will add to this post once I've done enough for it to be worth another picture!
