Patchwork
Jacob's Ladder
A nine-patch of five four-patch units (corners and center) and four half-square triangles (the sides). The four-patch darks and the HST diagonals line up to form the climbing ladder; piece the five four-patches and four HSTs, then join as a nine-patch.

How it goes together
- Step 1
Cut your pieces
Cut each region using the dimensions in the cut table for a 12 inch finished Jacob's Ladder block. Standard 1/4 inch seam allowance is included.
- Step 2
Sew sub-units
Sew the smallest units first (half-square triangles, flying geese, four-patches), then build outward.
- Step 3
Assemble the block
Join the sub-units into rows or columns, then join the rows. Press as you go. Square the finished block to size.
