On the Quilt Worktable click the NEW QUILT tab and on the ribbon below, choose Variable Blocks.
The variable blocks layout is like Baby Blocks, except that the blocks can have unequal sides and angles.
To adjust the layout, click the LAYOUT tab.
The layout palette has slider bars for adjusting both the horizontal and vertical width of the cube’s top, and the vertical dimensions of the cube’s side. Great variety in the resulting layout is possible, and the best way to master it is by experimenting. There is no sashing option for the variable blocks layout.
