The teacher and best student tried their darnest to teach me geometry and teacher finally gave me a D
to get rid of me....lol When we had Trudy Hughes for a speaker, she said "You use Geometry in quiltmaking"
I am so glad someone else does the math. There were some ladies at a LQS and were having trouble
getting their points nice....and I told them that what I do is add 1/8th of an inch to the measurement that
calls for 4 7/8" and cut a 5 inch square to make half square triangles and that gives me a litte room for
error in sewing...and then cut the square the right size; she said can I share that with some friends?
and I said ofcourse...lol I told friends the same thing when they were having trouble with HST.
the rule is add 7/8 to measurement for HST and 1 1/4" to make quarter square triangles.
Hope this helps. Also told that top student, he should have taught me quilting along with geometry...
and he laughed, when we had our 30th class reunion.
