I agree - a quilter can never have too may shelves. I keep all my books in large, clear storage bins w/the lids on so they can be stacked. I find I don't need those as much as I do the fabric so if they are more out of the way, that's OK for me. I stack the books in the bins w/the ends showing & all turned the same way so I can quickly see the title/author. I use smaller boxes/bins for projects in process or "smaller" scraps sorted by sizes. Also have bins for selvedges & pineapple strips. Hope this helps.
