When people ask me for pattersn for my pincushions I say I don't have one.
Truth is I don't. I just half sheets of 9x12 felt and cut them freehand into 6' 3' circles, strips and such.
This shows you how I divide it up three ways for a number of pieces.
THICK lines denote HALVING the 9x12 into 9x6 pieces... the thin lines show where I cut again with my scissors after the initial splitting in half.
I do not measure anything. I cut squares then round off corners to make circles. I'm really good at that, hehehe.
