This week's block is Card Trick. I've always liked this block but never made it before. It is actually one of the block's in Carol's class "Anatomy of a Block" that I am teaching at Quilt University.

Card Trick

As you can see, I used bright colors for my block with a black background. It uses the same pieced units as I have used in several other blocks.

A half square triangle unit.

HST with QSTs

And a quarter square triangle unit.


You can refer back to Ohio Star which gives you instructions on how to make these units.

I made a 6" finished block so I needed 3" squares and 3 1/4" squares. From the four colors I needed two of each and from the background fabric I needed four of each size. This does make more units than required, but it is easier than cutting individual triangles. 

I started with the half square triangle using the smaller squares. They are easy to chain stitch together.

 For the trimming I used my Triangle Square-up Ruler.

It is so easy just to put the 2 1/2" line on the seam and trim both sides.

Then open it up for the perfect 2 1/2" square. Just need to trim those ears off.

Next I used the larger squares to make the half square triangle/quarter square triangle unit. There are four different color combinations. I used the Square-up ruler to trim these too, this time I aligned that center seam with the diagonal line on the ruler as well as the 2 1/2" line along the seam.

Last I made the center unit which was the quarter square triangle unit and I lay them all out ready to stitch together.

These amounts made two reversed blocks and I still had some units left as well.

Can you see the difference? The blue is to the left of the red above. Below it is to the right.

Some leftover units too.

Perhaps tomorrow I will make another block or two.

  • I have always loved this block and have made it many times. Making as HST and QSTs is a much better way than with little triangles - would be much more accurate.
