Probably a blue nylon sheet......

No really, aren't most modern fabrics a blend of some sort.

Where's the other fibers?

They were only looking and notating common fibers from DW's environment...so if purple or polka dot fibers were on the sheet but not in his environment...they weren't comparing....according to their own testimonies.

I wonder if they checked the garage (playroom) for Danielle's fingerprints, traces, etc. I bet not.
