Maureen there are a few ways you can apply frit, my favourite is to use a stainless steel egg cup, turn it upside down and tip a little bit of frit into the well of the foot and just roll it in it.
Sprinkling only really works for the really fine powder like stuff anything larger and it just goes EVERYWHERE......I know
You can heat the end of your rod and dip it into the frit and then wind the bead too youget fantastic striations that way.
Steer clear of using ivory glass as a base though nearly all frits just turn black on it.
