Here are a few "drawings" that I've made from jpg photos I found on the web.
NB If the pictures don't display, right click on the placeholder and choose Show Picture.
WF brush
Vacuum machine
Pressure washer
They are dead easy to make with free software that you've probably already got. You may be able to use other software.
Step 1 - open your jpeg file in Microsoft Photo Editor
Step 2 - go to Effects, Edge and choose Thick or Thin as you want. Play with both and you'll soon find out which you need.
Step 3 - save the result as a bitmap. Close the file.
Step 4 - find the bitmap and open it with Paint.
Step 5 - save the bitmap as monochrome bitmap
Step 6 - still in Paint, save as a GIF file if you want to put it on the web.
And the job's done!
This is great for producing single-colour flyers as they print much sharper than jpegs.
