At the nibs and ink blog, be sure to go to the Labels on the right side, and click on [flourishing]
Then, you have to scroll down and start with the first post, at the bottom.
There are lots of tips - but I will mention the one that I think is the most important....
Don't try to learn all of them at once.
There is a fluidity to flourishing that only comes with practice and spending time making the motions with your whole arm
and not just wiggling your fingers.
Making tight little corkscrews or pigtails are OK if you want a very quirky, naive style. But, if your goal is to have flourishing that is elegant, you will do better with larger, loopy, ovals that compliment the ovals and angles in the particular style you are writing.
I have about 50 more exemplars to post ....and hope to get them posted one of these days.....
I will post to the forum when I get around to it.
