Diamond kit numbering sizes and types I've seen

 

I feel the larger visible alphabet one is easier but let's see how it goes. I'm starting an easier one now .

Let's see how the output comes even if it takes a few years. I've got a few kits i wanted to try doing.

One is alphabet alone. No stone placing circles

One is with circle and alphabet etc. stone placing is marked but alphabet has become smaller.

One type it's got a semi transparent sort of circle and alphabet not too small .

But anyway, it's sticking small stones onto design so it's bound to be small precise numbering. 

Just my thoughts here. From the types I've seen.
