Copic Markers

Have any of you used Copic Markers?  I received a set for a Christmas gift and I have to say I am hooked.  I've been working with them and love how easy they are to blend.  I haven't felt that there was much of a learning curve  but have just really spent some time familiarizing myself with the them.  I think that they are so much like painting that my thought process with them isn't that different.  I just recently completed some of the leaves similiar to the Jewel Tone Leaves that I have been painting and will post them soon.  Keep an eye out for my next post.
