Barbara Brackman’s Block Base calls this one Scrap Zig Zag. This is block number 19 out of 35, so we’re over half way there.
Cutting Instructions:
Medium fabric: cut 4 rectangles @ 2 x 3 1/2 inches
cut 2 squares @ 2 3/8 x 2 3/8 inches
Dark fabric: cut 4 squares @ 2 x 2 inches
cut 2 squares @ 2 3/8 x 2 3/8 inches
Draw a diagonal line on the wrong side of the medium 2 3/8 inch squares. Pair these up, right sides together with the 2 3/8 inch dark squares. Sew a 1/4 inch seam on either side of the drawn line. Cut these apart on the drawn line and press towards the dark fabric.
Pair these triangle squares with the 2 inch dark fabric squares, making sure that they are turned as shown in the photo below.
Pair these units with the 2 x 3 1/2 inch medium fabric rectangles, as shown in the photo below and sew together.
Go here for the finishing instructions, keeping in mind that the outer large triangles are dark fabrics.
