Quilts and Other Stuff from Frances

The numbers don’t lie

The other day while I was at the gym…..tell me if you have heard this one!!! HAHA……

Seriously, while I was on the treadmill, I was watching a Youtube video from “OnPoint-TV” as she presented the formulas for calculating the setting triangles for a quilt set on point. Interestingly, I found that I needed those exact calculations less than 24 hours after watching the show!!

So, in case you might need them…..

For the top and side setting triangles…..

Start with the FINISHED size of the block….multiply by 1.414…..add 1.25…….round up to the nearest 1/4 inch.

For my quilt, the calculations looked like this…..

That square is cut across both corners, making 4 setting triangles…..

Calculating the corner triangles…..

The calculation of the corner triangles has one additional step……

Start with the FINISHED size of the block…..multiply by 1.414……divide that number by 2…..add .875…..round up to the nearest 1/4 inch……

This block is then cut diagonally to provide two corner triangles…..

In the past I have figured out the size of these triangles by trial and error. It was freeing to be able to do the math and not have to guess!!

    1. You and me both!! When I took my exam to become a CPA back in the 1970’s you couldn’t use a calculator on the test…. 5 parts of 4 hours each!! It was sad that I was worrying if I had added 2+2 properly instead of the principal behind the question!!!
