Triangle quilts might look challenging, but they’re actually quite simple especially if you are working with equilateral triangles! This quilt is super fast and easy to make, but looks difficult because of the strips in each triangle.

When we saw the Amalfi Collection by Rifle Paper Co. for Cotton + Steel we couldn't wait to create this quilt with it! The line features fun summer prints, from girls lounging in the sun to whimsical waves.

Instructions

*Note: Seam allowance is 1/4”, unless noted differently

Cut each fabric into 4.5”x WOF strips (width of fabric). Separate into High Value (HV) and Low Value (LV) piles.

Sew two HV strips together down the length of the fabric; press seams open. Repeat for all remaining HV fabrics and again for all LV fabrics. Try to mix the fabrics so no two fabrics are matched together.

Using the equilateral triangle ruler, align the top point and bottom edge, or 8.5” line on the ruler, with the strip; cut. Flip the ruler around, align the diagonal edge of the ruler with the 60* cut edge of the strip; cut. Continue this way until you have cut all the triangles you can from this strip. Repeat for all remaining strips. You will notice that this will result in a triangle with a smaller triangle in the corner.

Using the photo below as a layout guide, place the triangles on your design wall, table or floor, alternating between HV and LV. Place the small corner triangle in the upper left for the LV pieces, and to the bottom right for the HV pieces. You will start to see a secondary half hexagon pattern emerge. Repeat until you have 21 triangles in the row.

For the second row, place the small triangle of the LV piece in the bottom right position and the HV in the upper left. Keep arranging the rows as described above until you have ten rows of triangles. Use the finished quilt photo at the top of this post for reference as you go!

Once you have all the triangles arranged to your liking, you are ready to sew. Place the triangles right sides together and stitch. You will have 1/4” of the edges sticking out on top and bottom, but once you have two sewn together, the pressed seam allowance will create a "seam guide" to lay the new triangle upon.

Repeat until all triangles in the row have been stitched, making sure to press the seam allowance open before sewing on a new triangle. Sew and label each row as you complete them. This will make it less confusing when you go to sew the quilt top together.

Sew all the rows together, pressing seam allowances open. Using the rotary cutter and straight ruler, trim the zig zag edges from the sides of the quilt.

Your new quilt is now ready to be quilted and bound! That was easy, right? The hardest part of this quilt is getting the perfect layout, but even that part isn’t so bad when you’re working with such pretty fabrics!
