This was not as easy as it seemed. I follow a lot more than three blogs and to choose ONLY three to share is just, well, really hard! But apparently three is the magic number and in this case I'll consent to playing by the rules. Here are three I have found helpful:
The Bookshelf Muse - This blog goes beyond the thesaurus, delving into the particulars of character emotions, color, and weather, to name a few. An indispensable tool.
The Practice Room - A virtual office and a quiet place to practice for an hour then connect with other writers afterward and discuss your work. I try to go on Mondays from 8-9pm but there are practice hours during the day, too.
Word Play - Another great resource for writers. Recent posts include: 10 most common mistakes, reading with attention, and the benefits of outlining, which inspired me to give it a try.
