Help with F4 pattern

I have a friend who wants an F4 carving. I found a line drawing and have tried turning it into a png and playing with gaussian blur and other things but the pattern is just not coming out very good. Can someone with more expertise or someone with pattern editor who can clean it up try turning this into a pattern for me? Thanks I appreciate it. I tried attaching the PNG but it keeps turning it into a JPEG.

See if this is what you have in mind.

Sure yes, do you have a ptn? I am not at home to try importing to designer but with the shading and all I might be able to do it. I will try it tonight, thanks.

Thanks for the help with the grey scale pic. a few touch ups in paint.net and some gaussian blur and it came out good. Here is the ptn in case anyone else can use it later. I am not the best at this so I am sure others could do better.

Enjoy, Greg.

G, anytime. We all help each other here. Kind of a family thing. Good luck!!!
