📏 Finished Block Size

12″ x 12″ (12½” unfinished)

✂️ Materials Needed

All fabric cuts are based on 42″ usable width of fabric:

• (1) 2½” x 30″ strip in solid green

This block is perfect for using precut 2½” strips (jelly rolls) or scraps from your stash!

🧵 Step-by-Step Instructions

Step 1: Sew the Strip Set

Place the three 2½” x 30″ fabric strips side by side (as shown in Diagram 1) and sew them together along their long edges.
Press the seams all in one direction.
👉 You now have a strip set measuring 6½” x 30″.

Step 2: Cut Squares

Cut the strip set crosswise into four 6½” squares (refer to Diagram 2). Each square will show the three-color stripe pattern.

Step 3: Assemble the Block

Using the layout in Diagram 3, rotate and join the squares in pairs to create a woven effect.
Sew the squares into two rows, then join the rows together.
Press the final seam in one direction. Your block should measure 12½” square unfinished.
