Well honestly, a trunk seems just like putting them in the basement or boxing them up. Once they're in the trunk are you really going to be pulling them out and looking at them?
I have mine on bookshelves and even then they don't get looked at all that often, but it does make me feel better to have them out! ;)
I started digital scrapbooking a few years ago and I will admit the creativity and quality of my books has gone down! But I'm limited to time and space with two small kiddos and it's my best option right now. In the last few years on line sites and apps have gotten pretty good though. I'd check it out! It's a lot less messy!
