Most of my patterns are packaged nearly the same size so I bought a plastic storage bin and I stand them up in it. I can flip through it to find what I'm looking for.
If I have a project going (a big one) I will use a notebook and put the finished blocks (8" and under) in a sleeve until the quilt top is finished.
I also have a block of the month that I did the same thing for. I put the pattern and fabrics in a sleeve until finished.
(I have a lot of notebooks). LOL
