Free PowerPoint pencil drawings
I eagerly followed Jeff Kortenbosch's drawathon and was able to reproduce most of the images with various deviations. I then began looking into creating vector graphics using InkScape and iDraw. I followed a number of tutorials and came across one at Vector Cove on drawing a pencil. I wanted to see if I could adapt the steps for PowerPoint. I've attached the PowerPoint with a number of images. You are free to use for whatever purpose you like.
