Go to www.bamagazine.com and download the free pdf of how to create letter logos. You'll get some good ideas from it. I don't subscribe to the magazine, but it looks like a great resource. If you want to see an example of a TLC logo saved at 300 dpi on a canvas of 746 x 746 (2.487" x 2.487") enlarged to 19.893" x 19.893" and enhanced to reduce pixelation, follow "size matters". I think 2.487" x 2.487" is correct, although I have 6.217" x 6.217" written elsewhere. ART
Update... ~update~ after a closer look, i found that there was only 4 that were available for download for free. all the other design tips were for "subscribers" and "back issues" are $8-$10.50 each...oh well.
