Traditional pattern, public domain. Published in numerous 19th-century pattern catalogs.
A dynamic block composed of four-patch units and half-square triangle units arranged to create a diagonal chain or staircase effect when multiple blocks are set together. The visual 'ladder' emerges from the interaction between adjacent blocks.
Jacob's Ladder is one of the oldest named quilt patterns in America, dating to the late 1700s or early 1800s. Its name comes from the biblical story of Jacob's dream of a ladder reaching to heaven (Genesis 28:12). The pattern traveled westward with settlers along the frontier.
This pattern has been known by many names depending on the region and era. During the Underground Railroad period, some oral histories associate it with signals for freedom seekers, though historians debate this. In political contexts, it was renamed for various candidates and causes.

| Piece | Fabric | Cut Size | Qty | Notes |
|---|---|---|---|---|
| A | Dark | 3 1/2 x 3 1/2 inches | 4 | For four-patch units |
| A | Light | 3 1/2 x 3 1/2 inches | 4 | For four-patch units |
| B | Dark | 6 7/8 x 6 7/8 inches | 2 | Cut once diagonally for HSTs |
| B | Light | 6 7/8 x 6 7/8 inches | 2 | Cut once diagonally for HSTs |
Pair one dark 3 1/2 inch square with one light 3 1/2 inch square, right sides together, and sew along one edge. Repeat for a second pair. Press seams toward the dark fabric. Sew the two pairs together, nesting seams, to form a four-patch. The unit should measure 6 1/2 inches square. Make 2 four-patch units.
Tip: Chain-piece the pairs for efficiency — feed them through the machine one after another without cutting thread.
Pair each dark 6 7/8 inch square with a light 6 7/8 inch square. Draw a diagonal line on the wrong side of the light square. Sew 1/4 inch from each side of the drawn line. Cut on the line to yield 2 HSTs per pair, 4 HSTs total. Press toward the dark and trim to 6 1/2 inches. You need only 2 HSTs for one block.
Tip: The extra 2 HSTs can start your next block — save them!
Lay out the 4 units in a 2x2 grid. Place four-patch units in the upper-left and lower-right positions. Place HST units in the upper-right and lower-left positions, with the dark triangles oriented toward the center diagonal.
Sew the two units in the top row together, then the two in the bottom row. Press the top row seam to the left and the bottom row seam to the right so they nest.
Pin the two rows together, matching the center seam. Sew with a 1/4 inch seam and press the joining seam open to reduce bulk. The block should measure 12 1/2 inches square.
