Once I even out my edges, I initiate my edge finishing in the following manner.
I select the appropriate edger depending on the size and shape.
I sand the edges using sandpaper or grit sticks seen in the photo. If necessary, use a gum eraser to remove an sandwich glue residue.
I then dampen a section of the edge and rub Glycerin bar soap.
I take a piece of heavy canvas material or a piece of denim. I rub some soap onto the piece before using them. I then use the canvas and rub the edges. What I am doing is creating heat and friction to deal the open pores left on the edges.
I take a dauber and light the tip on fire. When it has burned out, I use a piece of paper or napkin and remove the burnt ashes. I then select my choice of dye and apply it using the dauber.
I take a used cloth...in my case an odd white sock that my dog got a hold of. I take this cloth and rub the edges to remove any excess dye. If necessary, I will reapply the dye a second time.
I would than wipe the edges again with the cloth and rub it down with the soap covered piece of canvas or denim.
I the take my custom Dremel sized hardwood slicker and run the slicker over the edges.
Finally, I will mix 1 part of wax and 2 parts of resolene. I take another prepared dauber and apply the mixture to the finished edge. (The last three steps can be repeated if necessary, but I have found that the sanding will usually make or break you.)
Note: For any special mixture, I use the little salsa cups usually found at take out restaurants.
