Janice recently acquired some 60 degree diamonds and asked for tips on sewing them together. I wanted to make a mug rug, so I decided to create a tutorial and kill two birds with one stone. Here are my scrap diamonds.
I cut them with this die for my Accuquilt studio cutter. And that leads to my first tip, you must cut accurately. However you choose to cut your diamonds, due to the angle, errors are multiplied.
Next I decided on my layout.

I’m sewing this in columns. Here is the column on the right in the photo above laid out in sewing order.

When the pieces are placed together to sew, the dog ears should be off set by 1/4 inch at the top and bottom.

This next photos should give a clearer idea of what I mean.


That little “V” is where your needle should be when starting the seam.

If the offset is correct, when you open the seam, you will have a straight row without any jogs.

As you practice, you can line this up by eye. Until then, check with a ruler. This is wrong.

After adjusting, this is ready to go.

If it helps, you can draw the seam line as shown below.

I don’t use any puns when sewing these diamonds. When I’m done with the columns, I press the seams in opposite directions as shown below.

This allows my seam allowances to best together.


This is how the intersections should look when pressed.

I trimmed my piece down when I was done sewing. I’ll share this little finish after it has been gifted.

I hope this was helpful. Have a great day!
