I think Technique Tuesday tiles are wonderful. I'll choose them over brown or gray chipboard any day. The most important reason is that they are an ivory color & accept ink, paint, & even chalk so easily. The color comes out true, not altered by the darkness of regular chipboard. I also like how smooth the edges of the shapes are. They don't have the little knob-like pieces where the shape was attached to the surrounding tile. Even though the tiles are sturdy, they do cut easily. For instance, I cut the scallop circle into 2 pieces, to attach each piece to a separate page. Finally, I think they are a good buy because you get so many pieces in a package.
