Big T Quilt Block – Free Big Block Pattern

I have made the Big T quilt block as an 18″ square.  There are quite a few blocks named T but this is a particularly pretty one in my view.  It is a very simple block to make and looks more difficult than it is.

Cutting requirements for the Big T quilt block

6.1/2″ squares:  one blue

6.7/8″ squares:  two blue, two white

3.7/8″ squares:  four blue, four white

3.1/2″ by 6.1/2″ rectangles:  four white

You need to make half square triangles with both the 3.7/8″ and the 6.7/8″ squares.  Place a blue 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 gives you a pair of half square triangles.  They are either 3.1/2″ square or 6.1/2″ square.  Press the seams towards the blue and trim the two corners where the fabric sticks out.

The layout for this block is so simple that I’ll show you the full layout without any steps on the way.

Place the 6.1/2″ blue square in the middle with a white rectangle on each edge.

In each corner place a large blue/white half square triangle with the white on the outside forming the corner of the block.

Outside each white rectangle place two small half square triangles.  Place these so that the two white triangles side by side form a larger white triangle pointing in towards the middle.

In order to sew the block together, first sew the small half square triangles together in pairs and sew this pair to the white rectangle inside it.  You now have three rows of patchwork pieces which are simple to sew together.  Sew the rows to each other to complete the Big T quilt block.

Quilt Ideas

For the basic quilt idea I have shown nine blocks sewn together in three rows of three.  Considering how easy the block is to make, I think that the quilt looks satisfyingly complicated.  It’s a good one to impress non-quilters!

Alternate quilt design

Alternate quilt design

For an alternate design I have used a block made using half square triangles.  For these I made half square triangles from 9.7/8″ squares.

I think that this is one of the rare occasions when I actually prefer the basic quilt design to the alternate.

  1. This proves that sometimes simple is better – both versions are very appealing to me.

  2. Hi Rose Yes I must agree with you that the basic quilt looks a lot more impressive than the alternate. Of course it doesn’t have to be all blue and white as each block could be made in a different colour combination which might or might not look good. Maybe toning colours running from blues into greys. Just a thought.

    Hope you are enjoying this continuous sunny weather we are having.

    all best Janny

    • Hi Janny. Great idea to use shades of colour – it would look great. The sunny weather has been wonderful – even staying warm in the evenings which doesn’t always happen.

    Absolutely striking…blue and white…my absolute favourite. My son just moved to Toronto Canada and is busy buying furniture for his new apartment. I think this pattern in black and white will look striking on his new grey couch. Thanks Rose…you continue to inspire me with your wonderful tutorials.
