I’m so sorry to do this to you, cause am convinced that I have seen the pattern on this site, but I cannot find it again.
Its a lattice scarf, and the pattern went something like
R1 yo, k2tog repeat
R2 k to end
Repeat
But I can’t remember if that was the exact pattern, and there was also some detail about edges of it.
If it helps I think it was knitted in cream.
