Lace Front Wigs? New to Drag, so curious between wig types.

I have what is I assume, shake'n'go wigs. Can someone explain to me about lace fronts etc? I certainly couldn't show the wig line in the wigs I have. And yet sometimes I see it and I think 'Oh ratchet couture. Stunning!'

But no seriously what are your tips on wigs, info about wig types etc etc.

Thank!
