There are indeed a few Ben Franklins scattered about, I was just on a cruise to Alaska and visited one in Juneau that is much as I remember them from my childhood -- but in my child's eye they were huge even though I don't think they really were.
Again, as I understand, the name is individually franchised so each store is a bit different.
The ones here in Redmond and Monroe are really craft stores more than 5 & Dime of days gone by. Fabric is probably less than 1/4 of the store, but I always enjoy their selections. Because of the small space they offer some pretty good deals on last year's fabric/bolt ends (especially the Redmond store) and I always find something I like.
I sent Crispy a PM that mentioned that the Ben Franklin and the Pacific Fabrics are probably the best places to get specific Seattle/Washington fabrics. I really enjoyed getting fabric as my souvenirs of my Alaska trip -- it packs well!
