True to its name, Scrapbook Dreams sells everything you would ever need to build a scrapbook: fun edged scissors, fun shaped hole punchers, Mrs. Grossman stickers, gel pens, beautiful papers, etc.
And entire wall is covered in rolls of stickers and they're sold by the sheets.
Most of these things are fairly expensive (and it's not the store, this stuff is pretty much expensive everywhere), but sometimes if you're lucky, their sale rack will be stocked with clearance papers and such.
Scrapbook Dreams also offer scrapbooking classes year-round. There are holiday themed classes, calender specific classes, and so on.
