I don't know if anybody has done this, or can help me out at least.

This (http://www.helloyarn.com/bigskulltote.htm) is the pattern. I've cast on the 80 stitches with double yarn and knitted the first 18 rows putting the markers where it says. This means (well how I've done it anyway) its just in one long strip.

I've now come to the skull bit and using the white yarn but i'm in a bit of a pickle about this. There's a lot of yarn dragging round the back then when i do the next row yarn is dragging round the other side. I've never used 2 shades at once before so I don't know if i'm making sense or not.....

I'd use two separate small balls of white for each bone. So it doesn't stretch across the 20 stitches.

Ta! I've undone all of it cos it should have been knitted in the round!
