Mini-Tutorial: No Waste Granny Square Quilt Blocks

No one likes waste, especially of fabric. When you’re making Granny Square blocks out of 2.5″ squares, a bit of waste isn’t really that big of a deal. But I bought 2 Summersville charm packs to use for huge Granny Square blocks, and the thought of throwing away all that background fabric waste was enough to persuade me to look for a better way.

In a way, a Granny Square block is a small on point quilt. The finished sizes of the inside ‘blocks’ determine what size triangles you need to make those outside components. Quiltville has an excellent article about the maths of On-Point quilts, which is where I got the information to make this block (& tutorial).

The ‘block’ size in this tutorial is 4.5″ square (finished) – if you are making yours larger or smaller, I recommend printing the Quiltville article. This quick tutorial is for using 5″ charms.

What you’ll need for one block:

  • {13x} 5″ x 5″ charms for the centre
  • {2x} 7 5/8″ x 7 5/8″ background for side triangles (I used black)
  • {2x} 4 1/8″ x 4 1/8″ background for corners

Cut the LARGE squares twice diagonally. Yield = 8 side triangles. Cut the SMALL squares ONCE diagonally each. Yield = 4 corner triangles.

Here’s the layout. Sew the centre squares together into strips, then add the side triangles. The middle (longest) strip will need 2 of the corner triangles, and then you can add the other corner triangles where you need them. The triangles are intentionally sized generously so you can trim to a generous 1/4″ on the sides. I promise you won’t have to trim very much.

Ta-Da! And with the On Point maths already worked out for you, you can adjust this mini tutorial to accommodate any size of square.
