BEWARE BEWARE BEWARE!!!!
The dye in these sheets are so corrupt and staining that NOTHING escapes its power.  I went to pull my sheets out of the dryer and the dye stained the plastic ORANGE on all moving parts.  I had to use a magic eraser, then scouring powder to scrub it off.  
The dye method is going to punish you.  If you were attracted to the vibrant colors, then expect them to transfer to your skin if you don't wash prior to use, and your machine.  I washed my sheets prior to using them and I'm glad I did, but SHOCKED at how it stained my machine. 
Proceed with caution.
