I like these linen albums. I'm trying to find something that would hold 500 photos. Would one of these do it? As part of this question, more specifically, could I double up on photos on the clear photo pocket pages? * So if one page can hold 6 4x6 photos, could I put 2 in each slot, back-to-back so that each page then would hold 12 photos? If that were possible, would one of these binders hold 42 of those clear pocket pages? Also, structurally, would these linen binders be strong enough to support the weight? Or would the leather albums (We R memory Keepers albums) be stronger and better for that? Alternately, do you have another product that you might recommend for helding at least 500 photos? I'd greatly appreciate your help! Thanks in advance.
