This 12.5” x 12.5” block will require 6 different fabrics; 4 for the outer rings, 1 for center ring, and 1 for background.
(*Use the following direction as a suggestion. Cutting each piece one by one will result in more accurate result but you can save time by minimizing the number of cuts by cutting multiple pieces at once.)
a. Outer rings
1. Cut 1.25” wide strip of Outer Ring Fabric. A strip of half yard fabric should be sufficient.
2. Fold strip to make 4 layers of 1.5”. Cut all four layers into 1.25”x1.25”(A-2)
3. Fold remaining strip into 3 layers of 3.75”. Cut layers into 3.5” x 1.25” (A-1)
4. Repeat for other 3 remaining outer ring fabrics and separate each fabric into 4 groups.b.
b. Center ring
1. Cut 1.25” wide strip of Center Ring Fabric. A strip of half yard fabric should be sufficient.
2. Fold strip to make 4 layers of 1.5”. Cut all four layers into 1.25”x1.25”(C-2)
3. Fold remaining strip into 4 layers of 3.75”. Cut layers into 3.5” x 1.25” (C-1)
1. Cut 1.25” wide strip of Background Fabric. A strip of a yard fabric should be sufficient.
2. Fold strip to make 3 layers of 4”. Cut all 3 layers into 3 sets of 1.25”x1.25”(B-3). You will have 9 pieces.
3. Fold remaining strip into 4 layers of 4.25”. Cut layers into 2 sets of 2”x1.25” (B-2). You will have 8 pieces.
4. Fold remaining strip into 4 layers of 3”. Cut layers into 2.75”x1.25” (B-1)
5. Cut 8” wide strip of Background fabric. A strip of half yard fabric should be sufficient.
6. Cut strip into 2, 8”x8” pieces. Take both pieces and rotate by 45 degrees. Cut the 8”x8” into 4 triangles (B-4).
Arrange outer ring fabric into 4 sets in the order of how you want the rings to interlock. Select one set as the current outer ring. You will sew the pieces into 4 individual panels. The 4 panels will be sewn together to form a whole interlocking ring panel.
• After sewing each piece, be sure to iron both sides of the fabric, pressing the ¼” seam allowance to the darker fabric side.
• All sewn strips will be ¾” wide. Measuring before sewing and after ironing will result in seams that will line up evenly.
• Carefully align and pin seams prior to sewing.
1. Sew B-1 (background) to top of A-2 of next outer ring set.
2. A-1 of current outer ring set to the left side of the pieces
3. B-2 to the bottom of the pieces then set aside the pieces.
1. Sew B-3, A-2 of next outer ring set, B-3, and C-2
2. Sew C-1 to the left side of the pieces
3. Sew B-2 to the top
1. Sew first group of pieces to the 2nd group
2. Sew A-1 to the top
3. Sew A-2, A-2 of next outer ring fabric, and A-1
4. Sew last group of pieces to the right
Repeat the steps for the next 3 panels to create 4 panels.
*The last panel will use the first set of outer ring fabric for the “next outer ring set” for A-2.
1. Combine the 4 panels by first sewing the last B-3 to the bottom right corner of first panel. *Leave 5/8” un-sewn on the top to sew the final block.
2. Sew 4th block to the bottom of 1st with B-3. Turn 90 degrees to line up the patterns.
3. Sew 3rd to the 4th and then sew the 2nd onto the 3rd.
4. Sew the 2nd block to the 1st block. Be careful to line up the seams of B-3 from step one.
1. Sew B-4 to the top of the interlocking rings. Leave 1” un-sewn on the left edge, fold and pin.
2. Turn 90 degrees counter clockwise and sew the next B-4. Trim the corner edge remaining after a B-4 piece is sewn to each side of the interlocking rings leaving the ¼” seam allowance.
3. Continue sewing B-4 to each side of the interlocking rings. After sewing the last B-4 piece, unfold the pinned edge, sew together and trim edge corner. You will be left with a large square about 13” x 13”.
4. Trim all four sides, aligning the center of the interlocking rings, measuring 12.5”x12.5”.
5. Relax and enjoy the completed interlocking seasons block.
