Pros : LS is a fun medium to work with, and gives you new techniques with frit. Keeps it sticking where you want it.
Cons : I buy my frit pre-crushed and sized and no matter how careful I was, the mix kept clogging in the squeeze-bottle tip. So I guess this would be best for people who sift their own frit. I keep a straight pin handy to clear the tip.
Other Thoughts : The balance between frit and medium is tricky - a little too thin, and it runs everywhere. I never did get nice, thick clean lines like we see in Delphi's product listing.
