QUILT BLOCKS PATTERN – SOUTH DAKOTA
The South Dakota quilt block has ended up so large that I will probably be able to make it into a lap quilt quite easily. The finished size is about 31″ square. This is a nine patch quilt block attributed to Hearth and Home which was published at the beginning of the last century. The quilt block is constructed by making a nine patch panel from pinwheel blocks and plain squares and then turning this panel on point and adding a patchwork triangle to each side of the nine patch panel.
Cutting requirements for the south dakota quilt block
ten 4.7/8″ squares in both white and dark blue
four 8.1/2″ squares in light blue for the nine patch panel
for the triangles you will need two 5.7/8″ cream squares, one 6.1/4″ square in each of the cream and dark and three 6.1/4″ pale blue squares
Making the south dakota quilt block
The middle of the south dakota quilt block is made using pinwheel blocks and plain squares to make a nine patch panel. To make the pinwheel blocks, lay a white and a dark blue 4.7/8″ square with right sides together and mark a line along the diagonal. Sew a 1/4″ seam either side of the marked line and cut along the line. This produces two half square triangle units. Sew four half square triangles together to make one pinwheel. You will need five pinwheel blocks for the south dakota quilt block.
Make a nine patch panel as shown with the top and bottom rows having a pinwheel at each end and a plain square in the middle. The middle row has a pinwheel with a plain square on either side of it.
You now need four patchwork triangles – one for each edge of the nine patch panel. They are the corner units of the south dakota quilt block. The half square triangle at the top of the triangle is made from a 6.1/4″ square each of dark blue and cream fabric sewn together as above for half square triangles. Make four of these from two squares each of dark blue and cream. The two 5.7/8″ cream squares are placed underneath the half square triangles. Beneath them are three triangles made by cutting 6.1/4″ squares along one diagonal.
Sew these patches together in rows and then sew the rows together to make a triangle. Make four of these and sew one to each edge of the nine patch unit already madel.
This completes the south dakota quilt block.
