Last night as I was falling asleep, I was watching Fons & Porter - the one with Joseph's Pinwheels.
They said something about cutting quarter triangles and half triangles, so that the bias is not where............. getting really drowsy. LOL
Anyway, they said cut them so they don't have the bias on one side, so you don't stretch it out. And they told how big a square to cut out, based on the block it is being attached to. It all made sense as I was falling asleep, but now I can't remember exactly what was said. And it seemed so much more clear than I had ever heard it before.
Do you know what they said?
