I bought a roll from profleece a few of years ago(enough to carpet my house lol!*rolls eyes*), it was a little stiff to begin with but softened after a few 40c washes.
The pieces from that roll are still going strong as 'regular' bedding for the adults.
I bought a smaller amount of fleece(not profleece) off of ebay and dispite claims from the seller that it was of equal quality to profleece, it most definately wasnt! The backing was thinner, didnt wash as well, wasnt as dense. Thankfully I only had a singleton pup to use it on, I'll be ordering more from profleece for the next litter.
So be careful what you buy off of ebay!
Also make sure when buying smaller pieces or pieces to cut up, that you will have large enough bits to cover the floor of your whelping box with no gaps. Bare in mind the need to avoid waste too, so you dont end up with annoying scrappy bitty bits :-D
