Get an archival grade portfolio from amazon. One 18X24 (most in this) and one bigger eventually. This will allow them to be stored flat and you can flip though it like a picture book when you want haha. This is the one I use https://www.amazon.com/Itoya-Profolio-Evolution-Storage-Display/dp/B000H7N4H2/ref=mp_s_a_1_1?keywords=18x24+archival+portfolio&qid=1563215754&s=gateway&sr=8-1 and it’s been great.
