Wooden disks and Sharpies

I found wooden disks for ten cents at a craft store and decided to see how well Sharpies would write on them. The markers bled a bit, but by varying how hard I pressed, I could control the bleed somewhat. Applying the lighter colors before sketching any black lines works best, or else the black will bleed like a victim on CSI. Applying a light coat of spray acrylic before drawing also stops future bleeding, but it will turn the wood a couple shades darker.
