My first was corduroy squares sewn together with a white sheet for the backing. This was way back in 1970 and I didn't really know what I was doing. None of the squares had been pre washed and the first time it was washed all the different colors bled onto the backing. It really turned out great though...the back looked like it was tie dyed. It was made for my son's bunk bed and he still has it...kinda worn but still hanging in there.
