Daily painting storage

It turns out when you paint daily or most days you end up with alot of paintings! I’m experimenting with ways to work and store my paintings. I love the result of consistency painting a small painting most days brings, my skills and confidence have increased.But I have storage issues. I love hanging the new fresh paintings on my walls but the wall space fills quickly. My solution is to store the small canvases flat and bound together in series or date order, my hope is this will make it easy for me to refer back to them when I need to. I will see how this works.
