I love the Heidi Swapp cb alphas. They are a great size and color. The adhesive really stays put. It's a large package, so you can use them on lots of projects.
I really like the size and font of these letters. They take alteration (paint, distressing, ink) very nicely, or are pretty to use as-is. Another reviewer noted that they don't stick very well; I actually like this, as it means I can peel them off their backing paper and move them around on a LO before I decide where to place them permanently.
These letters are super cute but they are rather difficult to snap out of the pack without bending them and the layers of chipboard start to peel apart. They look great, but I was disappointed in the quality.
