The interlocking chevron quilt block is lovely because it creates the illusion of depth with the chevrons crossing over each other. I’ve made it here as a 57″ square quilt using four rows of four 12″ blocks – two rows of green chevrons and two of blue chevrons, with all of them having a light brown chevron interlocking. I have used about 2 yards of white, 1.1/4 yards of brown, 1 yard of green and 3/4 yard of blue fabric.
Cutting requirements for each chevron quilt block
four 3.1/2″ white squares
two 3.7/8″ squares each of brown and white and two each of blue (or green) and white
two 4.1/4″ squares each of white and blue (or green) and two each of brown and white
four 3.7/8″ squares of brown and of blue (or green)
Making the chevron quilt block
The first 3.7/8″ squares listed are used to make half square triangles. 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 to produce two half square triangles. These are both 3.1/2″ squares. Put these aside so that they don’t get mixed up with the half square triangles used in the next step which are slightly larger.
The 4.1/4″ squares are used to make quarter square triangles. Place two of them with right sides together and make half square triangles as above. These will be 3.7/8″ squares. Place these right sides together with a plain 3.7/8″ square and mark a line along the diagonal – that’s the opposite diagonal from the seam. Sew a seam 1/4″ either side of the line and cut the line to produce two quarter square triangles. These are 3.1/2″ squares. The two squares are not the same as each other so you will use one of them in the chevron quilt block and put one aside to be used in the quilt border. For each quilt block you need two squares made using a plain blue square with a brown/white half square triangle, and two squares made using a plain brown square with a blue/white half square triangle.
Lay the squares out in four rows of four. There’s a 3.1/2″ white square in each corner, four blue/white half square triangles and four brown/white half square triangles in the middle two columns and the quarter square triangles on the sides of the quilt block. Check the photo carefully to be sure that you place the quarter square triangles correctly. Sew the squares together across each row and then sew the rows together. Make eight blue blocks and eight green blocks.
Making up the chevron quilt
Sew the chevron blocks together in fours – two blue rows and two green rows. Sew the rows together alternating blue, green, blue, green. At this stage the quilt top measures 48.1/2″ square.
The chevron quilt border
For the first border cut five 2″ lengths of green fabric. Make up two lengths of 48.1/2″ for the top and bottom and two lengths of 51.1/2″ for the sides.
For the second border, sew together lengths of the quarter square triangles put aside when you made the quarter square triangles for the quilt blocks.
You should have enough for four lengths of sixteen quarter square triangles. You actually need seventeen for each side of the quilt, so sew a 3.1/2″ square somewhere along each length. Sew one length to the top and one to the bottom of the quilt. Sew a white 3.1/2″ square to each end of the remaining two lengths as cornerstones and then sew these to the sides of the quilt.
That’s the quilt top complete and ready for layering, quilting and binding.
