Sure!

fuckbees makes, in my opinion, the most beautiful Merlin graphics on tumblr, and in her description box, you can see that she runs a lot of other Merlin blogs as well for you to follow. 

mcmorgans is just fantastic and sweet, and for a big MerMor fan like me, she is perfect to follow. She also has links in her description box to follow.

Hope this helps! :)
