I got my DS a brand of bedding called Duck. My DS is three and half know but back then you could get it at Baby Co. He had bright green sheets, and muslin wraps in a red, blue, yellow and green (very bright-non pastel) which came in a pack. I also got him a Fire engin red pure wool blanket (came from Spotlight) which had bright blue blanket stich around the edge. DS's cot was white also and it looked really lovely. So different from all the pastil looks out there, which were nice also but just not for me.

Good look on your search.
