Underground Railroad

Week 21 of Barbara Brackman's Civil War Sampler quilt is called Underground Railroad.
... well, that's the 'modern' name for the block. I always thought it was called 'Jacob's Ladder', but I just checked it out in Brackman's own 'Encyclopedia of Pieced Quilt Patterns' where it is # 1312, and it is - according to this magnum opus - called : Hour Glass; Railroad Crossing; World's Fair; Jacob's Ladder; Double Four Patch; Railroad; Going to Chicago; New Four Patch; Gay Scrap Quilt; OR, Buckeye Beauty.
In Denmark (my country) we have a saying that : beloved child has many names.
Must be a seriously popular block.

The block is fully inklingoable in both sizes, tho' you need more than one collection to make it. The 3" HST (for the 6" size) and 4" HST (for the 8" size) this block calls for, are both found in the sold-out CD # 1 collection, but both sizes are available for download; in two different collections, but still :-)
