There are basically two types of drills; the round and square one. For the round drill, round shaped diamond beads are used and for the square one, the square-shaped diamond beads are used. The ‘full square’ drill looks like a ‘mosaic’. Many prefer this art as there is no space between the diamond beads and the image portrays a clean picture with sharp lines.
The ‘round drill’ looks like the ‘cross stitch’. For the small paintings, this is the ideal drill type. Some prefer painting with this drill as there is free space between the diamond beads and they are shinier.
