Dave, Good start!! But I would start more like this so you don't have to hand draw so many details. To get here, you can manipulate your image using "colors" "curves" in GIMP
Hope this helps

Dave, I arrived at that image by manipulating it using "curves" immediately after step 13 of the tut. BTW I don't ever use the sliders in photocopy.
This thread may be of value to you http://stevedgood.com/community/index.php?topic=12339.0
No need to be sorry, you are not being a pain ::)
Keep on practicing, you will get it.

OK Don, now you've confused me (not at all hard to do). Steps 10 through 13 in the tutorial deal with "photocopy" . You say to use "curves" after step 13, but also say you don't use the sliders in "photocopy". So do you skip 10 - 13?

Pete, I import my desaturated image into photocopy then click OK. If the result needs adjustment to get a nice gray and white image, I use  curves to adjust it to go from the attached image a to image b.
Did I confuse you further?? ;D

Now bring it back into GIMP and using your black and white paintbrushes, clean it up and get rid of the floaters then import back into Inkscape and do a trace bitmap at about .58 threshold, then print it out, cut it and post the results. easy Huh!! ::)

Don thanks very much for your help I dont think I will be cutting that pic but will practise some more and post the results as and when.
Just to clarify, I was confused when you said that you use curves after step 13. I dont have a step 13 and assumed that this was equivalent to step 5 in section B
I now realise that I was sent a updated version of the tutorial and you where referring to the original
this is what I have
Gimp
1.   File?Open
2.   Image?Mode?Grayscale
3.   Paintbrush?removes background by using various sizes of white brush.
4.   Filter?Artistic?Photocopy and go to full size image.  Use the sliders to manipulate a potential pattern. Pay close attention to the eyes and nose areas. Do not worry about blotches or skin tones as they will be removed in the touchup stage. You may need to use layers to achieve optimal details. Click OK.
5.   Paintbrush? use black and white and different size brushes to ?clean up? the pattern.
6.   Paint bucket? flood the background with black to check for floaters. Ctrl Z to go back.
7.   Save as (Export)? name file and save as JPG.
8.   Close Gimp

Inkscape
1.   File?New (window)?Letter (A4 = Metric) Close 1st window.
2.   File?Import (your pattern)
3.   Resize pattern to fit in paper size window by clicking corner and moving.
4.   Path?Trace Bitmap?make sure Brightness cutoff, Smooth and Stack scans are checked. Also make sure pattern is ?selected? in window by clicking on it, or trace does not know what to trace. Brightness cutoff between 550 & 750. When done click OK.
5.   There are now two images, one on top of the other.  Look closely to determine which the original was and right click to delete it.
6.   File?Save As?PLAIN SVG
7.   Close Inkscape.

Gimp
1.   File?Open the SVG file. Checkerboard image will show.
2.   Layer?New Layer?Layer Fill Type = White? OK. All white! Don?t worry!
3.   Layer?Stack?Layer To Bottom.
4.   Image?Flatten Image.
5.   Paint bucket?Flood background to check for floaters one more time.
6.   Use text tools to sign your new pattern.
7.   File?Save as (Export) GIF (smaller file) or JPG.
8.   Done.

Dave, that is my rewritten tutorial I sent you. The original (with the step 13) can be found here.

http://www.scrollsawer.com/forum/scroll-saw-design-tutorials/17249.htm

I shortened it from 48 steps to 23, and it has worked well for me. Some of the original was obsolete, because of the newer versions of Gimp & Inkscape I downloaded. Now I have to check out this "curves" business.  :)
Practic, practice, practice...
Pete
