I follow different kind of communities for layouts on LJ :3 you have to be a member of some though if I'm right :]
If you can't view entries just join the community and you should be able to see the entries of the different communities.
No special order.

Comment: There are all kind of layouts, simple ones and somehow really, how should I say..., different ones. Layouts which you can't really find anywhere else. Totally worth joining ♥

mintyapple Comment: A place where you can find lots of layouts. All varieties :] All colors. I guess this is the place where all the layout creators get together and post their stuff.

milou_veronica Comment: I really love the layouts there. The first layout creator I've ever stalked if I'm not wrong. I really like the somehow simple style which fits with the colors which are used. I can just recommend keeping an eye out for this person. I like using those layouts for my communities :]

minty_peach Comment: I see a lot of colors. Lovely layouts.
That mostly it. I stalk a lot of other communities/profiles as well, it's not that I think that they are not worth being mentioned, I just think if I don't stop here I'll just spazz again. Most important ones are mentioned aboth :3 I hope this helped.
