I think We R Memory keepers isn't making the 6x6 anymore. They're not listed on the www.weronthenet.com webpage anymore, and the sb.com store only carries 1 color now, and that's about out. I know because I wanted some and I had to SCOUR the internet to find them. So I bought 4 so that i'd have enough for the next few years.
They do make an 8x8 ring though, and since it's still listed on We R's webpage, it looks like they aren't stopping production. SB.com doesn't appear to have any, but they're out there. PM if you want to know where i found some.
might find a small notebook at an office supply store. I found and 8x8 post bound at a thrift store. I plan to put ideas in it so I don't have to worry about page protectors, just make pages out of card stock.
I agree, you should buy your page protectors at the same time your get your album (if you are doing a "real" project).
