I had seen the random marble placement of marbles in a fence and decided to create a cross. My awesome husband went to craft store with me where we found no marbles and decided to go with glass beads. We cut a couple of bead strands that were made for necklaces and bought a box of mixed beads. Awesome husband continued awesomeness by drilling all the holes for me after we drew a cross with a level for only a simple outline. The rest was freehand. Try it! It's fun and when the light gets behind it, the glass beads sparkle beautifully.
