This is a block that has given me much heartache , and that story deserves its very own blogpost! Meanwhile, here it is, Dozens Squared, the twelfth block of the Round the Year Block of the Month Quilt.

The block finishes at 18.5″ square (including seam allowance), with a 15″ inset circle. It is partly paper foundation pieced; the templates and instructions can be downloaded in PDF format from the links at the end of this post.
What’s in a name?
This Block 12 of the Round the Year BOM Quilt is inspired by the beautiful Jack’s Chain block. I couldn’t decide what I wanted to call it. I thought of something to do with 9-patches and then Jill’s Chain! But then I counted the number of pieces in the circle – 144. It could not be chance that Block Twelve should contain twelve twelves, could it? The name would have to to have some reference to this, I thought. No way I was going to call it ` Gross’, which is the correct nomenclature for a dozen dozens! Dozens Squared sounded better, also as the dozens would in any case be inset in a square!
Fabric Requirement
The fabric requirement for the block is given for the Dusk colourway. I have scrapped the block that I made in the Dusk colours (not this) – I thought it looked quite ugly (gross?)!

Please refer to the downloadable Instructions File, if you want detailed cutting instructions!
Printing Instructions
Please remember to print the Templates file with your printer
setting at 100% or Actual size in portrait mode. Cut out the paper piecing Templates.
I recommend printing also the Instructions file and keeping the Master Template (provided in the Instructions File) at hand when assembling the block. A line drawing version of the Master Template is also included in the file (also a mirror image ). You can use colour pencils to experiment with your own colour combinations!
Piecing Instructions
The Nine-Patches Quick Method
Piece the six 9-patches A, B, C, D, E and F using the quick 9-patch method. The pictures I am showing here are for the rainbow block. You will start with 3 pairs of 6 inch squares.









For the block we need 9-patches which finish at 3.5″, so we will need to trim these to 4″, with centre square remaining at 1.5″.

You could also use the template A to match and trim the 9-patches to size.

Piecing the Centre
I would suggest cutting the strips into triangles before you start piecing. Lay the 60 degree line in alternating directions as you cut the triangles – remember to leave 1/4″ on the top before you cut in the opposite direction.

If doing the Rainbow block, I may mention that a 6″ x 2.25″ yields 3 traingles quite comfortably. I used 8 different colours for the centre.

In no time, you would have the templates S, T, U, V, W and Xpieced. Put these aside.
Spiked Wedges
Now we come to the 12 spiked wedges G, H, I…Q, R.
Each of these wedges has 5 pieces. Before you start the actual piecing, I suggest you pin pieces # 1 (2.5″ x 1.5″) and #2 (HST 2.5″) on all the templates. This helps save time in sorting colours and sizes of the upcoming pieces!
Chain piecing must be the greatest innovation in sewing, don’t you think? In no time we are ready for piece#3, (which is the largest piece, at 2″ x 4″)


Trim the excess seam allowance.

Press open. Piece #4 is easy! Just align the long edges of the two pieces and sew!

Chain piecing, as usual!

We are ready for the last step – sewing piece #5 – a rectangle 2″ x 2.5″ ( I used 1.5″ x 2.5″ rectangles, but they made a tight fit, so I have changed the width to 2″.) Again, please check the rectangle placement before sewing to ensure you have the paper section fully covered.
All our piecing is done, all that remains is the assembly!
Assembly Instructions
Assemble the block, using the Master Template as a guide. Remember, the Master Template is a mirror image and shows the block as it would look from the printed paper (reverse) side. As seen here, what is on left appears on right and vice versa.
1. Sew the spiked wedge (halves) to either side of the respective 9-patches.
Sew G and J to opposite sides of A; M and P to opposite sides of C; H and K to opposite sides of E;
Sew N and Q to opposite sides of B; I and L to opposite sides of D; O and R to opposite sides of F.
2. Sew the centre pieced triangles to the 9-patch template sets.
Sew S to GAJ; V to MCP; T to HEK; W to NBQ; U to IDL and X to OFR.
3. Sew the respective circle edge wedges to the just assembled template sets. Here is some auditioning of fabric for the circle edges…
…before I settle on this!
4. Final Assembly
Option 1
Join background pieces AE1/ AH1 to wedge set containing A and B;
Join the background pieces AF1/AI1 to wedge set containing F and E;
Join background pieces AG1/AJ1 to wedge set containing D and C.
Join in threes – pieced set AE1, AF1 and AG1 to form one half; and the other 3 pieced sets to form the other half
Join the two halves to form the full block.
Option 2
Join the pieced sets to form the full circle and appliqué it to the background square using your favourite method.
Trim to 18.5″ square.
I am giving the Fabric Requirements for the Rainbow block in a separate blogpost.
