Jacks Delight Quilt Block Pattern

The Jacks Delight quilt block is made using a diagonal setting but as usual it isn’t too difficult if you take it in small stages.  I’ve made it here as an 18″ square finished size.

Cutting requirements for the Jacks Delight quilt block

5.3/8″ squares:  five brown, five white

6.7/8″ squares:  two white, cut along one diagonal

9″ square:  one brown

Use four each of the brown and white 5.3/8″ squares to make half square triangles.  Place a brown and a white square with right sides together and mark a line along the diagonal.  Sew a 1/4″ seam either side of the marked line and cut along the line.  This will give you two half square triangle units which are now 5″ squares.  Press the seam allowances towards the brown and trim the two corners where fabric sticks out.

Place the 9″ brown square in the middle of the layout.  On each edge of the square place two half square triangle units.  These all have a white edge against the square, but check the photo to be sure of which way to lay the half square triangles.

The layut shown on the right shows the block as it will lookwhen finished, although the photo below shows the layout as it will be sewn.

Outside each pair of half square triangles place a white triangle formed by cutting a 6.7/8″ square along one diagonal.  These form the corners of the quilt block.

Sew the patchwork pieces together in rows

Think of the block in terms of rows of patchwork pieces where the white triangle is the first and last row and the middle row has a white triangle at each end.

You should have two 5.3/8″ squares left – one brown and one white.  Cut them both along one diagonal.  In the second row place a white triangle at the beginning and a brown triangle at the end.

In the row above the bottom white triangle, place a brown triangle at the beginning of the row and a white triangle at the end.

For the middle section, sew the two half square triangles to each other vertically.  You will then be able to sew the white triangles, half square triangles and central square together in one row.

When you have sewn the pieces together into three rows, sew the rows to each other to complete the Jacks delight quilt block.

Just for interest, I then tried changing the colour in some of the blocks.

I think this second option gives a more interesting quilt.

  1. Yes, it was a VERY long time ago haha!

  2. Hmmm! Sure I’ve seen that brown and turquoise combination before….let me think. – oh yes, it was the colours of our school uniform – heh! Simple design and most effective – I agree, the second option looks superb.

    • June you’re amazing! I hadn’t made that connection with our school uniforms. What a long time ago that was!

  3. Hi Rose what an interesting block. I might just have to have a go when I’ve finished the quilt I am doing. It is taking a lot longer than I first thought but should be worth it when finished. A big problem for me is putting three layers together, but that is my problem and not for anyone else. At least I have now done something with all my scrappy bits.
    all best Janny

    • Hi Janny. I find that the only way to layer a quilt that works for me is to lay the wadding on the backing and start smoothing from one corner. I find that if I have the edges matching along the two edges leading out from that corner, then the rest will follow. Then I do more or less the same when I add the quilt top.

    HI Rose, the block has a nice layout, good contrast. I agree with you on the colors too.
    This would be an easy quilt to make. I am looking for a new pattern, this might fit the bill.
    Thanks for another great pattern. Always look forward to your mail.

    • Thanks, gentleenuff. The block is just that bit different, isn’t it, and it doesn’t take long to put together.
