Woven: A 3 Dimensional Quilt Using Half Square Triangles

This quilt is made entirely of half square triangles (HST)....lots of them! Make a test block first so you can see what the fabrics look like and if you even want to make the quilt.


Finished Size 72" x 96"

Fabric Requirements

2.5 yards of each of the following fabrics:
  • Black (Grunge Basics Onyx)
  • White (Grunge Basics Metropolis Fog)
  • Medium Grey (Grunge Basics Silver)
  • Accent (Grunge Basics Dynasty)
3/4 yds binding

The quilt has 12 blocks that finish at 24"
Blocks are set 3 across and 4 down.
Each block has 64 HST that finish at 3"
If you're counting, that's 768 HST in the quilt.

The Block
There are six different color combinations for the HST. There are two ways I recommend to make the HST:

AccuQuilt Cutting System 
  • Use Die # 55703 to cut up to 12 HST triangles at a time. There are no nubs to cut off when using this die! A great timesaver.
  • Want to try AccuQuilt without spending a fortune? Try the GO! Me Fabric Cutter.
Triangles on a Roll
  • Use Triangles on a Roll to quickly sew and cut your HST. This allows you to use large pieces of fabric at once so it cuts down the cutting time. One roll makes 600 HST so you'll nee two rolls to make this quilt.

The diagrams below show the block divided into 4 equal sections. Some people find it easier to follow this way.




This chart summarizes the fabrics and number of HST.

Here is a diagram of the block rows. I found this a great visual when laying out the rows. The arrows show the pressing direction for each row.

Here are some tips:

  • Check, double check and recheck the fabrics, placement and orientation of each HST before sewing any seams!
  • Cut and piece the HST for 1 or 2 blocks. Layout the blocks and make a test block first.
  • If you are happy with the test block, cut, piece and press all the remaining HST units.
  • Layout and piece 1 or 2 blocks at a time to avoid becoming confused or making mistakes.
  • Press the diagonal seams in the HST open. This reduces the bulk when sewing the pieces together.
  • When sewing the HST into rows, press the odd number rows (1, 3, 5 and 7) to the left and the even number rows (2, 4, 6 & 8) to the right. This allows the seams to nest when sewing the rows to each other.
  • Once the block is complete, divide them into two stacks. In one stack the seams are pressed up. In the other stack the seams are pressed down.  This allows the seams to nest when sewing the blocks together.

Block Layout

The diagram below shows the block layout.
  • The arrows inside each block indicate the pressing direction of the rows in the block. 
  • The arrows to the right of the rows indicate the pressing direction of the seams between the block in that row.


Happy quilting!
