On the transparent reds - if you are making just one bead it's fairly easy enough to strike, but if you have to make a matching set of beads, it's very difficult to get them all the same shade of red. Some will be lighter (orangey) some will be too dark, and some will have swirls of opaque in them. I despise all the reds for making sets, but maybe it's just user error on my part, and maybe not.
In other words, in my line of work I can make the same bead over and over again and make them identical, and this is what people know me for. But making a set of just simple rounds with transparent red?? Heck no!
