I live in Scottsdale, but have been to
Making Memories Unforgettable a couple of times. I love the place! It's been around for awhile, so they are well established and have quite a selection. I've also heard great things about
Pages in Progress, but I've never been there personally.
If you're ever in the valley, send me a PM! I made up a list of scrapbook stores and planned a route that took my sister-in-law to all of them in a 2 day time span when she visited. (With plenty of time to gossip and grab coffee in-between, of course.)
