My sister is an avid quilter, so she saves her tiny 100% cotton scraps for me to make paper from. First I sort the scraps by colour family. Then I stick them in separate fabric bags and wash without soap several times, since they have starches and whatnot that could affect the ph of the paper. After they've dried, I shred them into less then 1 inch bits with a rotary cutter. I'll post pictures of the rest of the process when I get to it!
