How to Sew a Grass Quilt Block (The fast way)

A springtime block made from two right triangles, with one little trick that turns them into cascading blades of grass.

  • Skill level: Beginner, confident
  • Technique: Two right triangles, cut and rearranged
  • Makes: One grass block (one of four in the Garden Grow wall hanging kit)

The finished grass block: cascading green blades against a soft aqua sky.

If you've ever looked at a pieced landscape block and thought there's no way I have the patience for that, this one's for you. A grass block looks like it took careful planning and a page of measurements. It didn't. It's two triangles and one clever rearrange, and it comes together faster than you'd guess.

No fussy math, no second-guessing your cuts. Just satisfying a block that leaves you with a block you'll want to show off.

Start with two right triangles

The whole block begins with two right triangles, one green and one soft aqua, sewn into a square. That diagonal line where the two fabrics meet is doing all the work: it's the angle that will read as blades of grass once everything's in place.

Slice the two-triangle square into vertical strips.

Then you slice that square into vertical strips. Right now it just looks like a striped square, so stay with me.

Rearrange the strips in reverse order

Here's the trick that does the magic: take your strips and lay them back down in reverse order.

That's it. That one move offsets the diagonal from strip to strip, and suddenly the flat green triangle turns into blades of grass leaning up toward the sky.

Reversing the strip order offsets the diagonal into blades of grass.

It's the kind of result that looks complicated and feels like a shortcut, which is exactly the good stuff.

Sew the strips together and press

Sew those vertical strips back together in their new order, press it flat, and your grass block is done.

That's a great springtime block, start to finish, without a single tricky measurement.
