Wool Blocks are colorful and decorative blocks made from wrapping Wool over Blocks of Wicker. As they are the same color as the wool used to make them, they come in 16 varieties. While they can be used as purely decorative blocks, they and their Wool Slab counterparts are often used as cost-effective ways to fill Block Dispensers to turn alternating Redstone signals into more complex patterns.
White wool blocks can be crafted with any dye to turn it into the matching color, or more efficiently a single dye in a cauldron will color 8 Wool Blocks. Potash in a cauldron will turn 8 colored wool blocks back to white.
