I believe the rules states you cannot advertise your bags for sale. You cannot post pics & link them to your listing on whatever site you're selling on. The admins are pretty strict on this. I don't know how things are done on the Shopping Resources or Bags, Bags, Bags forums.
As far as other designers, I've been looking at Givenchy, Chloe, YSL, Celine, & an Italian designer of Massaccesi leather handbags. There's a thread for Massaccesi in the Handbag & Purses forum. They not outrageously priced as some of the other designers I've been looking at.
I do think MK had a banner year last year & it's hard to follow that. I've been watching his Collection series & haven't seen anything that really moves me. IYKWIM
What I've seen on another forum is where one tpfer will post another tpfer's auction. Just a thought.
