Dumbarton Oaks
Designed by: Jinny Beyer
Instructions and graphics by: Kathryn S. Ramirez
Finished Quilt Size: 76 1 /2" X 76 1 /2" or 91 1 /2" X 91 1 /2" • Finished Block Size: 15"
For best results read all instructions before beginning. All seams are 1 /4" – All strips are cut the width of the fabric, except as
instructed otherwise – carefully trim all selvedges.
Jinny’s selection of fabrics in Dumbarton Oaks, features the perfect gradation of color with different color values from light to
dark and furthermore achieving a subtle shading and adding more dimension in the overall quilt design.

Getting Started
The construction sequence for the two quilt sizes listed
above will be exactly the same. The only difference are the
measurements that are used to cut the strips in preparation
for creating the borders and the number of pieces needed
to create the correct number of blocks. As you work through
the instructions, take care to select the measurements and
cutting amounts that will result in the size quilt you desire.
Yardage and cutting instructions for both colorways are the
same. Diagrams are shown using colorway #1 and are not
to scale. The measurements and cutting amounts given in
each of the steps are for the 761/2" square quilt. To make
the 91 1 /2" square quilt follow the measurements and cutting
amounts given in parenthesis (#).
1. Make templates for pieces A, B, and D from a
see-through template material. Make sure to add a 1/4
inch seam allowance around all sides of each piece.
Label each template and mark the seam allowance
on the template as well.
2. Cut four - 1 1 /2" x 92" (1 1 /2" x 107" ) strips from the length
of fabric #4 for second border.
3. Cut 92" (107") from the length of the border fabric and set
aside to create your borders in step 15.
4. For piece A, fussy cut each square on point by centering
the template on one of the motifs in the large floral fabric
making sure the flower is just inside the sewing line.
Mark some portion of the design directly onto the

template to use as a guide for cutting the remaining
pieces. Carefully draw around the template and cut out
the piece. Repeat 16 (25) times for a total of 16 (25)
pieces. (Approximately one-half of the squares will have
their flowers reversed.)
5. For piece B, follow Jinny’s instruction for bordering a
square quilt, Piece A.
Diagram 1
• Cut a 1 3 /8" strip from the border print fabric centering
the diamond shapes shown in Diagram 1 in the center
of the strip.
• Place the strip of the border print across the middle
of the square (piece A), centering a motif from the
border at the exact center of the piece as shown in
Diagram 2. (Measuring across the middle as opposed
to the edge is more accurate.)
Diagram 2
• Use the template created for the piece to mark and
cut the miter along both of the edges. (If you have
centered a motif from the border print correctly in the
middle of the square the designs should match at the
edges.)
• Mark some portion of the design directly onto the
template to use as a guide for cutting the remaining
pieces. Cut 64 (100) identical pieces, making
sure that the design on the border print is exactly the
same on all 64 (100) pieces four for each of the 16 (25)
blocks.
6. Piece C is rotary cut. Cut strips across the width of fabric
(from selvedge to selvedge).
• 10 (16) - 23/8" strips of fabric #1
• 8 (13) - 2 3 /8" strips of fabric #2
• 24 (38) - 2 3 /8" strips of fabric #3
• Fabric #4 will be 30" wide or less depending on the
accuracy of cutting the second border from this fabric.
Cut 11 (17) - 23/8" strips from the remaining width (from
selvedge to cut edge) of fabric #4.
• Cut 23/8" squares from all strips.
You will need:
• 160 (250) squares from fabric #1
• 128 (200) squares from fabric #2 and #4
• 384 (600) squares from fabric #3
• Cut all squares in half diagonally to form half square
triangles.
• 320 (500) half square triangles from fabric #1
• 256 (400) half square triangles from fabric #2 and #4
• 768 (1200) half square triangles from fabric #3
7. Piece D, center the template on one of the motifs in the
border print fabric, making sure that a line from the
border print falls just inside the sewing line on the long
side of the triangle template.
• If you want to see what a square of the motif will look
like before actually cutting the pieces, position the
template onto the fabric, then place two mirrors on the
two short sides of the triangle so they meet at a right
angle. Carefully remove the template to see what the
finished square will look like. By simply placing the
template in a slightly different place on the fabric many
different squares can be cut from the same border
strip.
• Mark some portion of the design chosen directly onto
the template to use as a guide for cutting the remaining
pieces. Carefully draw around the template and cut the
pieces out. Repeat 64 (100) times (four for each
of the 16 (25) blocks).
8. Making Blocks
Create Unit 1

Unit 1

• Sew the borders (4 B pieces) to the squares (piece A)
starting and stopping 1/4 inch from each end and then
sew the mitered corners together. This creates Unit 1 as
shown in Diagram 3. Repeat 16 (25) times.
9. Create Unit 2:
• Sew four triangles (Unit 2) to each square (Unit 1) to
create Section 1 as shown in Diagram 8. Repeat 16
(25) times.
11. Create Unit 3:

• Carefully sew together a triangle unit of C pieces
consisting of a row (Diagram 4) of one triangle of fabric
#3; then a row (Diagram 5) of two triangles of fabric # 3
and one triangle of fabric #1; then a row (Diagram 6) of
three triangles of fabric #3 and two triangles of fabric
#4. This will make Unit 2 pictured in Diagram 7. Repeat
64 (100) times.
• Carefully sew together a flat-top triangle unit of C
pieces consisting of a row (Diagram 9) of two triangles
of fabric #3, two triangles of fabric #1, and two
triangles of fabric #2; then a row (Diagram 10) of four
triangles of fabric #3, two triangles of fabric #1, two
triangles of fabric #2 and two triangles of fabric #4.
This will make a Unit 3 pictured in Diagram 11. Repeat
64 (100) times.

13. Complete the Blocks
14. Assembling the Quilt
To assemble the quilt, sew 4 (5) rows of 4 (5) blocks and
then sew the rows together to form the center of the quilt
now measuring 60 1 /2"X 60 1 /2" (75 1 /2"X 75 1 /2"). Shown
in Diagram 14.

• Sew four triangles (piece D) cut from the border fabric
to the sides of Section 2 to create the block as shown
in Diagram 13. Repeat 16 (25) times.
15. Adding the Borders
Cut four strips - 2 7 /8"x 92" (2 7 /8"x 107") from the border
stripe fabric centering the facing double hearts as show
in Diagram 15 to use as the first border to the quilt.
Diagram 16

16. Cut four strips for the third and last border 5 1 /2" x 92"
(5 1 /2" x 107") from the border print fabric centering the
largest stripe shown in Diagram 16.

17. Create four strip sets of border strips by first sewing the
strips cut for the border from Fabric #4 in step 2 to the
strips cut in step15. Next add the strips cut in step 16 to
the strips cut in step 2. The strip set order is shown in
Diagram 17. Center the motifs from the border print
fabrics within your strip sets.
18. Then follow Jinny’s instructions for bordering a square
quilt.
Diagram 17
Diagram 18
• Place a strip set across the middle of the quilt or block,
centering a motif from the border print at the exact
center of the piece as shown in Diagram 18.
(Measuring across the middle as opposed to the edge
is more accurate, and will keep the quilt from "ruffling"
at the edges.)

19. Finishing the Quilt
Layer the backing, batting, and quilt top; baste. Quilt,
bind, and finish as desired.
Diagram 19
• Use a right angle triangle to mark the miter along one
of the edges, making sure to leave enough for seam
allowance as shown in Diagram 19.
• Carefully pick up the mitered edge of the border strip
set and bring it over to the other end of the border strip
set at the opposite edge of the quilt, making sure that
the design matches. (If you have centered a motif from
the border print in the middle of the quilt the designs
should match at the edges.) Cut the second miter.
• Using this first mitered strip set as a guide, cut three
more identical pieces, making sure that the design on
the border print is exactly the same on all four strip
sets.
• Then sew the mitered strip sets onto the quilt starting
and stopping 1 /4" from each side. Then sew the
mitered corners.
