Back to the Star Struck Quilt /cutting with Omnigrid Half Square Triangle(96L)
My strips are cut for both the 4” and 8” stars, and just to recall I have cut 1 ½” strips from both the star fabric and the background fabric for the 4” finished stars, and 2 ½” strips from both the star fabric and the background fabric for the 8” finished stars.
Now to cut the triangles needed for these blocks.
Let’s start with the 8” finished stars.
Using the 2 ½” strip of the star fabric I am going to cut the star points using the Omnigrid 96 half-square triangle ruler.
Why do I use the half-square triangle ruler? – instead of cutting 2 7/8” strips, then cutting into 2 7/8” squares, then cutting on the diagonal into half-square triangles. ARRG...that would be too many opportunities to get off on cutting!
The reason is with the triangle ruler we are cutting the triangles right away from the 2 ½” strips, instead of an extra cut or two, so it is more accurate. Each time a cut is made there is slight chance of error, and this eliminates two cuts.
So, line up the ruler with the 2 line (why the 2 line, because the finished measurement of this half-square triangle is 2”) along the bottom of the star fabric strip. You will notice a little yellow line at the top of the ruler, which lines up with the top of the strip. That’s the extra 3/8 of an inch we don’t really need.
Make your cut.
Pick up your ruler by that top point, turn the ruler so that little line is along the bottom of the strip and 2 line is along the top. Do your next cut.
To cut the background triangles, use the Omnigrid 98 ruler. Line up the 4 line along the bottom of the strip (why the 4 line, because the finished measurement of the long side of this quarter-square triangle is 4”). Make your cut. Turn ruler and make next cut.
For the 4” finished stars, we’ll repeat the cutting, only using the 1 ½” strips for both the star triangles and the background triangles.
After you have cut the background triangles, come back, use the same strip and cut the background squares. Nice! No need to cut another strip.
Get all the cutting complete, and next time we will do some sewing and pressing tips.
Here is a "How to" handout on each of the rulers – so they know what size strips to cut when the pattern tells them to cut 3 7/8” squares for half-square triangles or 5 ¼” squares for quarter-square triangles.
Have fun with Triangles!
