Plastic Alpha's Rock!
I love the HS plastic alpha's. I have used them on all kinds of projects. They are self-adhesive, which is nice and come in different colours and sizes. You can twist them off of the plastic or cut them - which ever you prefer. The only time I have a little bit of an issue with the alphas is when they are mounted to the base in two places - they're a little bit harder to get off without cutting. But, all in all, I really like these and am glad I tried them out.
