They vary in size from a small flower being 1/2 inch to bigger paisleys 3 - 4 inches.
They have some with the OHM sign and some with cross. They also sell thin ones that can be used as a border. Below are some of the ones I have found if you are interested let me know and I will pick out the best ones I can find depending on what you want.
I found some larger blocks today so I am editing this post and adding the pics of them. They are aprox.5-6 inches high or wide depending on the shape by 3 1/2-4 inches.
These are most costly obviously more work involved.
