The Erase Block tool removes blocks already set in your quilt.
The Erase Block tool is available on all layers of any type of quilt.
The Erase Block tool is not recommended for Custom Set quilts, Layer 2, or Layer 3. In these cases, use the Adjust tool to select your block, then click the Delete button or your keyboard Delete key to remove the block. If you use the Erase Block tool on these layers, it will leave an empty placeholder.
Using Ctrl + click and Alt + click on some layout styles will not work the same as they do on Horizontal/Straight layouts. You may have to repeat the Ctrl + click and Alt + click to achieve the desired goal.
