I have some burlap targets that are approaching the end of their usefulness. I also have several yards of black burlap that I got for free several years ago. At some point the two entered my mind at the same time and that light bulb appeared over my head. Why not make new ones?
First I cut my black burlap to the appropriate size and sewed a hem all the way around. (Yes I sew regularly----what???)
Then I laid the old one over the new one keeping them together with some office type spring clips. The weave on the old one is open enough to poke a silver Sharpie through it to make a series of dots all the way around for a kind of "Connect the Dots" pattern.
Then it was a matter of drawing between the dots and adding some color. I used some extremely thinned acrylic paint that my wife and I use to paint inspirational rocks. (WHAT?? Yes inspirational rocks - get over it!)
I used a 1/4" artist brush and roughly painted in the colors.
