I took the set of Photoshop brushes known as "Wire Around The Bone", created by ~eggler, and converted them to GIMP format, with explicit permission from the original artist, of course! I'm too poor to afford Photoshop, and I'm no longer running stolen or illegal software (honesty, it's a trip!), so I use The GIMP. Get it here: [link] . Try it, try it, Sam I Am. You just might like green eggs and ham.
The original brush set for Photoshop can be found here: [link]
The original artist's webpage is located here: ~eggler
The zip archive containing all ten brushes in this set for the GIMP is located here: [link]
Drop these into your Gimp "brushes" folder & refresh your brushes to use. I do NOT provide user support for the GIMP or these brushes. If you need more help using them, please refer to the Gimp documentation. There is a TON of it available. Thanks!
These brushes are free for personal use. Refer to the original artist (~eggler) regarding permission for commercial use.
