I was in Michael's on Friday night, and actually looked at every one of those stacks! I had the black and white glitter stack in my hand, but then put it away, because I really wanted more shimmer paper. I saw the shimmer stack and that's what I bought. And then right next to it was the silky smooth paper and I fell in love! The paper has a wonderful finish, and is nice and sturdy. I bought both of those stacks. Before anyone thinks I spent a bundle, they were all 40% off, so I think I paid 36.00 for all three - it worked out to 36 cents per sheet.
I also saw the chalkboard paper and was very intrigued...one of the cute things they did with it was cut it into rectangles and put it on baskets, wrote on the cardstock with chalk, really cute effect.
