I think most of us have just found designers that we really like by seeign LO's in the galleries and other than that, I don't really look for a designer {I do the majority of my shopping here
{...and if you do the monthly challenges here you can earn points and then get a % discount the next month! you could probably find a majority of the designer population in the gallery at DST or MSA, since they have open galleries....are you looking for anything in particular?
