Half Square Triangle: Fussy Cut DIY Template

Fussy Half-Square Triangle

This morning I popped out of bed with an idea of a quilt I wanted to cut up. It was 6:30. I had today off. Why the rush? Most of the fabrics I wanted to use were pre washed, but three important pieces were not. And I don't have laundry in my building. And it was 16 degrees outside.


Too the bathtub I went!

To the Tub

I tossed in half-yards of some Lizzy House, Amy Butler and Sandy Gervais. Woolite. Warmish water (to help with the pre-shrink).

No dryer? No problem! The radiators were on and toasty warm. A fan helped circulate the air. About 90 minutes later, I was in business.

Dryer Dilemma: Solved!

I was ready to cut. And cut. And cut.

Peach and Pink Palette

When I got to the Sandi Henderson Meadowsweet, I knew I wanted to be verrrry careful. For this quilt I've challenged myself to tackle the half square triangle block. For most sewers, it's pretty basic. I'm intimidated by the bias sewing and a bunch of other jazz.  And I want to control exactly what appears on the triangle when the seams are sewn and pressed. Because you lose a half inch of the square, diagonally down the middle, when you sew it up, it's not as easy as imagining the square folded in half to get what you want.

"I need a custom ruler," I think to myself.

Well of course, I'll just make one!

Do It Yourself

First I traced out a 5 inch square on some template plastic. Then I drew dotted lines down the diagonal center, both directions. I wanted to know what part of the image would be lost by the center seam, to I drew a line 1/4 of an inch from the center line on either side.

Seam Allowances

I then drew a 1/4 inch boarder around the whole square--so I know exactly what fabric will be lost in the other seams.  I traced out my template with water soluble fabric marker like this:

Tracing the Square

See how the solid red diagonal line goes through the center of the flower? That's what I wanted. The top left triangle, when matched with a solid, will press open and look like a sun rising. That does mean the bottom right triangle will look different when pressed open, but that's ok. I'll save it for another project.

Bordering Brilliant!

So now my half yard of "vintage paisley" looks like Swiss cheese--if Swiss cheese was orderly and had sharp cube shaped bubbles. But it worked! Stay tuned.
