I'm really starting to enjoy R.C. Harvey's blog, Hare Tonic (via the Comics Journal).
His most recent article explores the use in comic strips of tables and such to give characters a "hand puppet" look...
"Here’s a picture we almost never see.
Garfield’s Jon Arbuckle at full height. Usually, he appears from the chest up, he and his forever orange feline positioned at a “counter” or some other horizontal surface, and we see them as if they were hand puppets."
To read the rest, go here.
Another blog I watch out for is Dirk Manning's Write or Wrong (over at Newsarama).
Write or Wrong is a regular column where Dirk gives pointers to comic writers. I have found his advice very informative and I like to read what he has to say.
The latest installment is titled "Wagon Hitchin'" and can be read here.
