There are many variations of blocks that can be created as a 16 patch using half square triangle units. The Yankee Puzzle Variation found at Delaware Quilts is a great example. This block uses 3 fabric groups with a factor of 4 for unit sizes.
When ever I begin choosing fabric for a quilt, I begin by deciding whether it will be scrappy or not. Mostly I consider any quilt to be scrappy when using multiple fabrics in a fabric group. For example, the Yankee Puzzle Variation has 3 fabric groups and I want to use more than one fabric for the light color group, I consider it scrappy. However, if I was just going to add a fabric group, lets say for example, have all the corner half square triangle units be a different fabric than the other light half square triangle units, then I would not consider that scrappy.
As a general rule of thumb for me, if there are more than about 12 or so fabrics used in a quilts, quilt blocks, I generally don’t spend a lot of time making sure each fabric “works” with each of the other fabrics. And the more fabrics, the less I even look at all. With a large number of fabrics I would just choose fabric groups either by hue (color) or lightness and darkness (value) or small, medium and large print (scale) or some combination of all three.
Here is a quick reference for making your own Yankee Puzzle Variation quilt block.
|Unit Method||Special Ruler|
|Strip Width by Finished Block Size|
The method used to calculate the half square triangle units strip width uses a half square triangle ruler, a.k.a. a side right triangle ruler, to cut from the same strip with as you would squares. See the half square triangle instructions for details of how to make this unit.
