The Jefferson city quilt block pattern is classified as a nine patch block. I have made it here as an 18″ square, finished size. It is made almost entirely from half square triangles, with just two rectangles in the middle. You could use a square instead, but I chose to use two rectangles in order to make it more straightforward when sewing the squares across the rows.
Cutting requirements for the Jefferson City quilt block
3.7/8″ squares: eight each in blue and white, four each in blue and lilac, four each in lilac and white
3.1/2″ by 6.1/2″ rectangles: two blue
Making the Jefferson city quilt block
Make half square triangles from all the 3.7/8″ squares in the colour combinations listed above. Place two squares 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 will give you two half square triangle units. Press the seam allowances towards the darker fabric and trim the two corners where the triangle tips stick out.
Lay the patchwork pieces out in six rows of six.
As usual, the trick is to look for larger patterns when checking to see if you have laid the pieces out correctly. When I first looked at this block my eye was drawn to the vertical patterns – the white diamonds down the columns and the lilac triangles forming a diamond around the blue centre of the block. However, when I looked at it for longer I found that the horizontal patterns are probably a better guide when placing the pieces: there are three shapes which I think of as either Christmas crackers or toffees. The top and bottom ones are the same as each other – the middle one contains the two blue rectangles and has lilac half square triangles at the ends.
Sew the squares together across each row and then sew the rows to each other to complete the Jefferson city quilt block.
For quilt ideas, I first tried just using sixteen of the basic block sewn together in four rows of four. I wasn’t sure if this was interesting enough, so then I tried adding some more colour within the blocks – as you can see I used a dark blue for the central rectangles in the blocks and tried a stronger colour instead of the lilac. In the end I actually felt that I preferred the first, basic version. It feels like a restful quilt to me.
