I am using the standard (Brenda's) and it came out to 4.5 unfinished. I took another look at my seams and they aren't really a scant quarter so am adding to the outside edge on this one (B5) and being really careful on the next and see what happens.
Also, after struggling half the day on the diamonds on this B5 I gave up and fused and am going to applique by machine. I tried reverse applique just for practice and didn't do that any better. I'll continue to practice and see how it goes!!
Part of my struggle with those tiny applique might be the loss of feeling in the tips of my right hand due to carpal tunnel. Maybe.
